Bro its literally 7 days, chill...

This is called a cooldown, and if by "help" you mean that someone in the VAC forum (where there are only regular users) will tell you how to shorten or remove this cooldown, then I'm afraid I have to disappoint you; that's not possible.

If your cooldown is longer, then you've probably already received one a few times, and the others haven't.

Ride it out Junior

Your cooldown is higher because you most likely played more with the cheater than your friends

Someone else is the one cheating, but I am the one who got a long sentence. Is this justice?
Yesterday, I was banned from competitive mode for 7 days and all my teammates were banned for 20 hours for cheating during the game. After the game, a user named Oldsnake admitted to cheating, but I didn't know about it while I was playing. Why was I banned for 7 days when everyone else was banned for 20 hours? I need your help. Watching the match will help you better understand who is using the cheat. Please help!

Why are Competitive cooldowns issued?
Competitive cooldowns exist to ensure that Counter-Strike matches are enjoyable for all players on the server. When a player commits actions which negatively impact the match and players in the match, they may receive a Competitive cooldown which keeps them from playing on Valve servers for a set period of time.

Competitive cooldowns will be issued regardless of whether or not an infraction was intentional and explicit warnings are given to players before committing an action that will result in a cooldown.

Competitive cooldowns are issued for the following reasons:

Failing to stay connected to the server
Any player who cannot remain connected or reconnect to the server in time will receive a Competitive cooldown. This may be caused by network, technical, or local issues with your machine, but any time a player leaves a Competitive server and does not reconnect in time a Competitive cooldown will be issued.

If you are experiencing network or technical issues that are causing Competitive cooldowns we suggest troubleshooting those issues before attempting to play another Competitive match. Please see our Troubleshooting Network Connectivity help article for more information.

Kicking too many teammates
Competitive cooldowns are issued to players who kick too many teammates in Competitive matches. Regardless of if you called the vote or only pressed 'F1' to kick the player, doing this too often will result in a Competitive cooldown for your account.

Cooldowns for kicking too many teammates are only issued to players abusing the vote kick option. We have a number of systems in place to ensure these types of cooldowns are issued correctly, and if you find yourself playing with abusive teammates we suggest reporting them in-game instead; calling votes to kick a teammate should only be done in extreme circumstances.

Being kicked from too many matches
If you are kicked from too many Competitive matches your account will receive a Competitive cooldown. Like kicking too many teammates, there are systems in place to ensure cooldowns of this kind are only issued to players being kicked an excessive amount.

Abandoning matches
Explicit warnings are shown to players who wish to abandon Competitive matches. Choosing to abandon an incomplete Competitive match will result in a Competitive cooldown for your account.

Users experiencing network or technical issues may be disconnected from Competitive matches, resulting in a cooldown for abandoning or failing to reconnect to the match in time.

Being AFK or not participating in matches
A player in a Competitive match who is AFK or not participating may be removed by the server. When this happens a Competitive cooldown will also be issued. If you find yourself needing to step away we recommend asking your teammates to call a timeout.

Receiving too many in-game reports for griefing
Players receiving an excessive number of in-game reports for griefing may receive a Competitive cooldown. A number of safeguards are in place to ensure these kinds of cooldowns cannot be abused.

VAC has flagged your gameplay as irregular
Players who VAC determines as having irregular gameplay will be disconnected from the match and receive a minimum one day competitive cooldown regardless of their current cooldown level.

Cooldowns issued for irregular gameplay prevent access to all game modes for the duration of the cooldown.

Note: players who receive a VACnet cooldown will have their CSR adjusted regardless of if they, or a player they partied with, caused the match to be canceled.

VAC flagged a member of your party's gameplay as irregular
Players who party with someone who is disconnected for irregular gameplay will receive the same minimum one day competitive cooldown as the disconnected player regardless of their current cooldown level.

Cooldowns issued for partying with a player who VAC disconnects for irregular gameplay prevents access to all game modes for the duration of the cooldown.

Note: players who receive a VACnet cooldown will have their CSR adjusted regardless of if they, or a player they partied with, caused the match to be canceled.

Can my Competitive cooldown be removed?
No. Regardless of the reason a Competitive cooldown was issued they cannot be removed from an account.

How long will my Competitive cooldown last?
Non-VACnet Competitive cooldowns in Counter-Strike 2 have four levels. When an account receives a Competitive cooldown, the cooldown level remains on the account for a one-week probationary period. Any additional cooldowns received during the one-week probationary period increases the amount of time players are restricted from matchmaking.
First cooldown (level 1) - lasts 30 minutes
Second cooldown (level 2) - lasts 2 hours
Third cooldown (level 3) - lasts 24 hours
Fourth cooldown (level 4) - lasts 1 week
A week of clean play will reduce an account's cooldown level by one. An account whose cooldown level has been reduced to level 2 through clean play would receive a level 3 (24 hour) cooldown on their next infraction.

Cooldowns issued by VAC for irregular gameplay are always for a minimum of one day and increment your cooldown level by 1.

Please note that cooldown levels can exceed level 4. Players whose cooldown level exceeds level 4 will need an extended period of clean play to have their cooldown level reduce beneath level 3.

How do I determine my current cooldown level?
Your current cooldown level can be determined by the length of the last non-VAC issued cooldown you have received:
My last cooldown lasted 30 minutes - you are currently at level 1
My last cooldown lasted 2 hours - you are currently at level 2
My last cooldown lasted 24 hours - you are currently at level 3
My last cooldown lasted one week - you are currently at level 4 (or above)
