DOUBLE TRANSACTION AND LOCKED ACCOUNT

Following my ongoing unresolved Double debit by AFRICAN BANK/FLYSAFAIR query I again made a lengthy call to African bank yesterday the 11th of August 2021 after I was told to follow this up with FLYSAFAIR which advised me that the transaction was not processed by them instead by my bank, I spoke to Mpho Polori who was not of much assistance and was quite irritated really (poor customer service) who informed me she escalated my matter to her supervisor Lerato Tsema who was supposed to give me a callback but hasn't and its been 24 hours and still no feedback from African bank who has since blocked my account after leaving me with a negative balance on my account for a transaction they are failing to account for! The issue here is not the money itself but the principle, as my bank how can you debit my account twice and say it was a delayed transaction yet you took money TWICE! I will not stop until my issue is resolved and my account is properly investigated. PLEASE TAKE THIS SERIOUSLY AS I HAVE LAID A COMPLAINT TO SA CONSUMER COMPLAINT AND AM WILLING TO TAKE MY COMPLAINT THE LEGAL ROUTE.
