I mailed by payment for Sam's Club Discover card 4 days prior to the due date, and I received a late fee ($15.99). The date the payment was received was one day after the due date, which is debateable since the payment was mailed to the state next to where I live. I called immediately after I saw the charge online and asked to have it removed. The $15.99 late fee was the only charge for the current month and since it was removed, the agent that I spoke with said I did not need to send a payment. However, I have been receiving phone calls from GEMB every 3 hours. I was unavailable to answer the calls but the message on my voice mail was "press 1". That was the entire message so I had no idea who it was from or why it was left. I had 4 of these same messages every day and since I was out of town, only received them when I returned. When I was home to answer, then I knew the caller and discovered the reason for all of the calls. GEMB agent said I needed to make a minimun payment since my payment was overdue. I explained that the charge had been waived and that I would pay before my next due date and was told I had no previous payment due. They said that I was correct and that they were sorry. The following day, 3 more calls were on my voice mail saying "press 1". I knew who it was, called and spoke with another agent who said I was delinquent with the last month's payment. I told them that this problem had been resolved with another agent the previous day and mentioned to them to stop the calls and harrassment. If I get any more "press 1" messages, I will cancel the card. They only reason I have it is because it is the only credit card that Sam's Club will accept.
