Wrong Debit order amount

I don't think you deserve even this one star. I had my policy reviewed on the 30th becauae i was leaving for FNB and I got a confirmation of the new amount via email yet this pathetic insurance debited me more money. I want my money back into the account you debited. I shouldn't have given you the benefit of the doubt because you don't deserve it at all. What's wrong with Absa??? This bank if it's not life cover then it's car insurance. I WANT THE EXTRA MONEY THAT YOU DEBITED. AND PLEASE DONT EVEN IF YOU DONT GET ME THROUGH THE CALL MAKE SURE THAT THE DIFFERENCE IS CREDITED BACK INTO MY ACCOUNT OTHERWISE I WILL GO TO FNB
