Other things to check/try. Log out of account, clear any cookies for Tesla's web site, and log back in. Check in your Tesla account the name, address, zip code and make sure they are the same as used by your CC, no mismatches. If still failing I guess you could also log out and try to purchase as a guest. Just to see if it is something like the CC in your account vs what you are entering.
