FNB NOT KEEPING PROMISES

In May 2019 FNB Debited my account that opened in 2018, I disputed the debit order, they accepted the debit order and sent me an sms confirming that my money would be relocated in 5 Working days. It has been 9 Working days and i spent an hour on the phone yesterday with FNB while i was at FNB, Just for a team leader to tell me that i will not be getting my money back, as i apparently gave permission in 2016 for them to debit an account that was opened 2018. I have (3) Three cheque accounts with FNB, I feel that this is completely unacceptable.
