Business ProfileforMazuma Credit Union

On August 13, 2023 at 3:38 am, I stopped by this ATM at the Mazuma Credit Union drivethru (MIDTOWN location. **** **** ******y, Kansas City, MO 64130, Phone: ************, ATM #*******) to withdraw $400 in cash on my ****** debit card. The machine gave me a receipt and my card, but did not dispense any cash. On the receipt, it clearly states "Transaction Denied", but I received an immediate notification from ****** that the money had been debited from my account. I reported this immediately to ****** and they opened up an investigation. I also called Mazuma Credit Union to report the malfunction, but was told that since I'm not a member of their bank, there wasn't anything they could or would do for me. They suggested I contact ******, which I already did. Days later, ****** made a temporary $400 deposit, pending their investigation. Yesterday, I received an email from ****** telling me that Mazuma had logs of this failed transaction and they were satisfied with the verbal guarantee that the money was actually dispensed and the case is closed. I requested that the case be re-opened and that Mazuma needs to provide an ATM log AND video of the transaction, because I'm now out $400 from the ATM malfunction AND paying another $400 out of pocket for the malfunction. ****** re-opened the case, but closed it this morning, stating they were satisfied with the proof Mazuma provided, although I have seen no proof at all and I have this little ATM receipt saying "Transaction Denied" and my ****** log of the same transaction. This morning, I went to the Mazuma location and asked to speak with a manager. Not only was I denied access to a manager, but they also declined to produce or provide ATM logs or ATM video of this transaction. Please help!
