UMB Bank Bank Account Or Service Complaint

UMB Bank Bank account or service department,

Checking account Using a debit or ATM card Missouri

On - -, I attempted to deposit a check ( for $500.00 ) at my bank 's ATM. The ATM would not allow me to deposit it so I left without completing a transaction. A few minutes later I received a text saying that $100.00 had been withdrawn from my checking account. I called the bank within 2 hours of receiving the text to let them know that I did not make that withdrawal. The bank employee assured me that they would review the video of the ATM and as long as I was n't the person who took out the money, they would refund the money to me. On - -, they sent me a letter saying that no dispensing error occurred and they were discontinuing the investigation ( without refunding my money ). They also sent me the ATM audit, which shows that the money was withdrawn at -, and someone immediately after me used a different bank card at the same time ( - ) without completing a transaction. Based on this information, to me it looks like it is possible that someone ( either accidentally or on purpose ) took the money out of my account instead of their own account. I called the bank on -/-/- to see if they were going to review the video of the ATM. They indicated that they would not review the ATM video and refused to give me a reason as to why they would n't investigate this issue.
