Billed for incorrect amount and no feedback receiv

I was debited for an amount of R498 in March instead of R298. When I called the contact centre I was informed that it was an error and that I would get a refund and somebody would contact me to confirm. To date nobody has contacted me regarding this. A few weeks ago Nur Williams phoned me to upgrade my contract. I queried this debit with him and he said he would find out for me and call me back the same day. I am still waiting.<br> <br> I am not happy with this. I do not have time to be calling the call centre and holding on for long periods of time to sort out your error. <br> <br> Somebody needs to contact me and get this rectified!!
