Does anyone send letters to cardholders that are abusing their debit card privileges? for example A cardholder who files Reg E claims(fraud) every few weeks. The purchases are at local restaurants where the transaction is card present, but he claims he did not participate in the transaction. If you send letters, would you mind sharing what you send? Thanks you.

After the first re-issue of the card after the first claim and then the second event, you would just not re-issue a card, so I am not sure why you need to send a letter.
