Business ProfileforTri Counties Bank

I discovered 4 fraudulent transactions in my checking account, supposedly from ********** The first one occurred 8/23/23. The next occured two months later 10/10/23 followed by two more transactioins 11/9/23 and 12/11/23. I could not find anything online with ********* or in my ********* account as to what these transactions were for. I called ********* and talked to their security department. They could not find any valid transaction within ********* by my banking account number or debit card numbers. ********* encouraged me to file a report with my bank and seek reimbursement from my bank. I have done so and ****************************** denied the claim, stating that it has been more than 60 days from the first transaction. However, I believe these are separate transactions because of the two-month gap between the first transaction on 8/23/23 and the second transaction 10/10/23. TriCounties should reimburse me for all four transactions because they are all obviously fraudulent. At the very least, Tri Counties should treat all of these as separate transactions and reimburse me for the last three on 10/10/23, 11/9/23 and 12/11/23. TriCounties Dispute ID is *****.
