Capitec bank overcharged me

I am closing my account, last month I did a transaction to Zambia and used the card number instead of a account number, I then went to the branch to ask them to recall the money (reverse) it back to my account, they agreed and said it will be return in the next 10working days and they gonna charge me R150 per transaction cause it was 2 transaction. The other one was R1560 and the 2nd one was R2 600. Yesterday I received the 1st transaction and they charged me R590.07 for that transaction cause they only returned R969.93. Capitec overcharged me and the agent that assisted had the nerve to say I didn't read the print lines that were never communicated with me. Open capitec account at your own risk!
