Unauthorised debit orders

It's the third month in a row Absa is debiting my account with a R 21.00. I want to know if my rewards is up to date why don't i receive rewards i also use my card to swipe every day and if i try to check my balance then my account is not showing on my internet banking and if i try to register then it say i'm already registered now why am i paying but i'm not receiving any rewards. I want my account to be reactivated i pay but i don't receive anything which is very unfair i always have problems with Absa the bank i have all my savings accounts and my transaction cheque account i don't mind paying the expensive fees. If my complaint is not solved by the end of tomorrows business day i'm closing all my accounts and switching to a other bank. I want to see my rewards account active on my internet banking with my current balance since i started paying the R 21.00 in April.
