FNB double charging on bank fees

FNB have charged me twice for the following:

#Service fees #Value added service fees #Non FNB ATM cash withdrawals #Monthly account fees

The above charges are charged monthly on my account on the 20th of each month. Their systems charged me again for the same fees on the 31st in anticipation of the new 15% VAT. When i ask their consultants to reverse the charges they tell me that its mandatory charges in line with VAT and they are charged at Pro-rata. They never consulted with me to have these fees charged on my account at pro-rata. It means the bank can do as they please with my money with/without my consent?? I asked them to reverse the 20th of March charges and leave the 31st of March charges, then the consultant cut the communication saying i was taking too long to respond on their banking app which is not true.

This is bullying of the highest order and i want my money reversed back or else i moving to another bank that will provide professional service with good business ethics.
