I keep recieving calls from Citibank Sears Mastercard days after my account was cleared up by the bank, and my amount due is zero. Yet I recieve calls several times a day from them. I called this number back, it is Citibank Past Due Dept. They said I owe zero. And they will take me off their list, but it will take 1 hour to do that. Only 20 minutes later, I recieve another call from this number. I'll see if the calls stop in another half hour.
Don't be afraid to call and complain. Sometimes it's just a matter of who you talk to.
