Absa exorbitant Admin Charges

Absa is a ****, my partner and I changed from FNB to Absa few months back and took Gold Value Bundle. Everything was fine in terms of charges until this month with me. Today I was charged R521 for Admin charges. This is exorbitant and was not part of the transaction fees. How can one jump from R41 in May and to R521 with no difference in transaction fees. Please reimburse my money back into my account or else I take my business else where. You are ******, my partner was charged +-R590 last month and he only became aware of that now when we are comparing fees and for this month it is R750. I need no explanations besides my money back into my account unless if you want to lose customers because I cannot deal with such fees more special in this economy.
