Credit card or prepaid card — M&T BANK CORPORATION (TX)

Problem with rewards from credit card. I am the executor/personal representative of my aunts estate and she passed away, on XX/XX/XXXX, with an outstanding balance of roughly XXXX points ( equivalent of {$880.00} ) on her M & T Bank credit card. I reached out to M & T Bank customer service to get information on the process to close the checking account and to get a check issued for the points balance on the card. I was instructed to deal directly with a branch representative ( no mention that there was an estate services division available to help with such issues ). I sent an affidavit on XX/XX/XXXX directly to the branch with attention to a specific representative, including instructions/inquiries on how to monetize the points on the account. I then followed up with at least 6 phone call
