FNB TOOK MONEY FROM MY ACCOUNT BUT DIDN'T PAY MY DEBIT ORDERS

On the 31st of December 2020 I transferred an amount of R10 000 for my debit orders that were to debit on the 1st of January 2021. On the very same day(31 December 2020) the amount due for my vehicle finance with MFC was debited. Today on the 2nd of January 2021 I received an sms from MFC that my finance account was in arrears, I called MFC to query this as the money had been taken from my account, MFC confirmed that the last payment received was on the 30th of November 2020. I went to the FNB branch in Menlyn Maine on the 2nd of January 2020 and two consults told me that the debit order was reversed BUT THAT SUPPOSEDLY REVERSED AMOUNT IS NOT IN MY ACCOUNT. THE CONSULTANT KHUVANGANI THEN PROCEEDED TO TELL ME THERE'S NOTHING SHE CAN DO AND I MUST MOVE FROM HER DESK. THIS IS STRAIGHT UP THEFT FROM FNB BECAUSE I DO NOT HAVE THE MONEY IN MY ACCOUNT AND NEITHER DOES MFC. THIS IS MESSING WITH NY CREDIT RECORD BECAUSE PEOPLE ARE ***********
