Unfair service

I have a personal loan with Absa, due to covid i was granted payment relief. After they relief I advised them to debit my account as I'm banking with them. Instead they handed it over to the attorneys. I received a call from them and made payment arrangements. To my surprise Absa debited R4000 from my account without my knowledge nor authority. As a bank my money is supposed to be safe with them. I called the ***** department as i didn't know what the transaction was for. And i was told to call the collections department which by the way they told me they can't assist me i have to call the attorneys to ask them to send proof of arrangements. I was told to call the complaints department if i have a problem. Was taken from pillar to post with my airtime running out 3 times. I visited the branch and was told to call the collections department. The service I received from MY TRUSTED BANK was uncalled for. We are facing difficulties during this pandemic period, and for someone or institution to be so inconsiderate is really not fair. I have not received any feedback or anything regarding my concerns yet i have been with the institution for so long. ABSA IM VERY VERY DISAPPOINTED!!!!
