Bad service

Goodday, I received an notice that my debit order will be deducted on 22 DECEMBER 2021, I contact Fnb to cancel it on their app...they continue to deduct the money, I reversed the deduction via their bankers on their premier chat group, I even go as far as reversed it myself on their app....I asked the banker afterwards why it's not deducted, she told me it will take 48 hours, until today it didn't happened. I send a complaint and told them I don't want it to be reversed anymore but want this issue to be addressed and also to compensate me for the inconvenience....their consultant told me, the only action they can take is to take me of the list of earlier deductions for 2022, how ridiculous. It's not my 1st or 2nd bad encounter with Fnb, I thought it will get better, believe me their service is BAD BAD.
