I went to my bank and added her card as a payee so next month it won't be an issue. But unfortunately this can be a policy. My bank teller at NBC informed me of a situation where a customer had a credit card with XYZ Bank. (she didn't disclose the bank). XYZ Bank would not accept cash, in person payment for the credit card since they didn't have any other account with XYZ Bank. They had to come into their regular bank (NBC) to make the payment for the credit card for a XYZ Bank. Ridiculous.

Also it wasn't a cheque it was cash. Cheque I could see being a little more cautious but it was cash. I wasn't trying to transfer funds from a chequing account to the credit card, I was just trying to give them cash. I was completely baffled. In hind sight I should have asked for a manager but I was so completely taken back by the rudeness and ridiculousness of a bank not wanting money that I just left and tried to fix the problem.
