This is a pretty big fail, but I've had this credit card for about six months now and I JUST found out that one number was off on my SSN when I applied for the card. I was trying to set up an account on the new version of their rewards site and the last four of my social kept showing up as "incorrect"... tried one number different and it worked.
So, my question is, how much does this affect if I let it go? Does this mean this card isn't affecting my credit at all, since credit reports will be using my actual SSN?
