Vodacom accounts department

Vodacom billing is completely useless, i called in on the 07/05/2024 to advise them that my bill is incorrect and if they can correct it before they deduct the incorrect amount. I was advised that a SR has been logged and got the email and sms. So just to make sure i call them a few day before the debt order should go off to confirm its been rectified and was told everything is in order and i would be debted the correct amount. GUESS what they ****( shocker) so i called them this morning @ 8 to get this sorted and all they can say is they need to speak to the accounts department and try and fix it( all good) so the supervisor on duty gets it sorted and says that she will email the credit note and still nothing. Once again i have to call in to try and get answers from them on there **** up. So i speak to another consultant and no answer as to when the refund will happen and request that a supervisor calls me back. Supervisor calls and i request proof that the refund is approved and i get told its not reflecting on my account and they cant send me any proof that the refund has been approved and been done as its an internal matter. Since when is taking the incorrect amount of money from someones account an internal matter. Vodacon needs to sort out there accounts department and get there **** together.
