African Bank stole my money!!

African Bank stole my money. I attempted to purchase electricity, but encountered an error during the process. Subsequently, I discovered that the funds were debited from my account, without confirming of a token or SMS notification. Upon contacting African Bank to address this discrepancy, I was provided with a token that had already been used. Additionally, I experienced a separate issue where a money transfer I made through the bank's app was duplicated, despite the recipient only receiving one transaction. African Bank attributed these issues to a system upgrade. Despite multiple attempts to rectify the situation, including contacting the bank, my funds have not been refunded. I request prompt resolution and the return of the funds owed to me.
