This is ridiculous, i've been with citi over 20 years and have 700+ fico scored, always paid on-time and pay-in-full, i have total around 60k credit with 3 cards combine, suddenly today i received a 3 letters saying all my account has been closed and don't give reason, have to write letter to the PO box address. This is so F up, what's going on? Anyone know what's going on? This is bad and not fair to consumer who has done nothing wrong and good credit. Can someone give me an answer? All my reward points cannot redeemed too once it's closed according to the stupid rude customer service.
