do as they please in my account

This was the same reason I decided to pay my credit card by hand with african bank because yes I know I'm in arrears but who gave the right to debit extra in my account than the agreed instalment just got an sms say they will debit an extra R93 in my account I don't have that money and I promise if you guy do debit that extra I will block you in my account and continue make payment manually and change my account you do even call me you just send an sms and tell me what you going to do. I reverse everything this just wait and see I'm tired of you guys I thought things have changed but you still do as you please<br>
