I mailed in payments to Citi on two different accounts at the end of June. Citi deposited them on 7.3, cleared on 7.5, and still hasn't credited the payments to my accounts. I've sent them sm, faxed the front and back of the check, and made innumerable phone calls, and nothing doing. They've said they have no record of the payment. I've also been told by sm that I'll receive a letter in the mail within 30 days about this, of course long after payment will be due. I'm so frustrated at this point, with my payment due this week. Any advice, anyone?
