Unable to change the card on my account
So I got a new card a while back with a new number and everything, but Steam seems to be refusing to let me change my old one. I kept trying to just click the "save my info for next time" button on each purchase, but it never actually saved the new info through that so I tried just going into my account to update it manually. I deleted the old card and tried to add the new one, but when I hit save it still saves it as "card that ends in ****" with the old number?? Even after fully deleting that one??? I'm at a loss for what to do or how to fix it. Any ideas?
