Never Citibank again
Charged me interest for being 3 days late-- ok, I get it. But then they charged me interest for the next month, paid on time. This is their policy. It just happened that that balance, the one paid on time, was huge because of some medical bills incurred unexpectedly, a big heating bill, etc. When I called them, they would not even consider removing or lowering the overblown interest charge (I have good credit; interest rate should have been lower anyway). I also spoke to a manager with no results.
I have been a customer for many years and always pay my bill on time. I also pay online, so they don’t have to deal with paper. I have cancelled my account. If I could rate them ZERO I would.
