INCORRECT BILLING ON MY ACCOUNT

For the last two months Vodacom has debit my account with R399 were my contract is only R299.<br> <br> I called the accounts department for them to sort this out for me and the lady said she would phone me back in 15 to 30 min and i am still awaiting for them to call me back. She said that the manager will call me back. This was at 1 o'clock today. The time now is 8:14pm.<br> <br> I want my account to be credited for the R200 i have paid extra on my Vodacom account.<br> <br> i am really not happy with Vodacom and as soon as my contract is done i will not upgrade my contract with them.<br> <br> Please can someone get back to me regarding this matter.<br> <br> I have herd that i am not the only one with this billing issue.
