Accounts Department

Vodacom double debited my account and now my other debit orders will be short paid as they took more than they were supposed to. I now have to wait for Monday the 4th for them to refund the money as they say their accounts department is not available today which i understand, but knowing Vodacom i doubt it will even be refunded that Monday. But what about my other debit order that is supposed to go through on the 2nd and the negative balance that is now reflecting in that account as they took more money than they were supposed to. This is really inconveniencing!! Your technical issues should not be my problem. I nowhave to make funds available to cover the negative balance you created and for the debit order that will go through on 2nd. NOW who will be paying me back the extra money i had to spend??
