Financial Abuse

I have been subjected to unnecessary and unexplained bank charges of R750.00 on the 01/09/2022, over and above the normal monthly service fee(s). This is unacceptable especially it does not even explain what the charges are for. This is too much, 750.00 is a lot of money to be taken by Absa just like that. I feel very prejudiced and ****** of my hard earned money. Can Absa refund my money ASAP
