MTN is *****ing my money

I have been billed over R+260 (Total). for Data (Hybrid and Recurring) for the past 5 months which I never received. Every time I query this, I am told that it has been escalated and I will be refunded and the MYSTERY service will be removed from my account. I have recently downgraded my package hoping that the issue will then resolve itself. I am surprised that I carried over the handset promo fee to the new contract and also the MYSTERY recurring data bundle which I have not requested, EVER.<br> <br> I have exhausted ways in which I can get this resolved as no one wants to take ownership. All previous recorded queries by the other Agents have either not been escalated or escalated to the wrong departments by their \competent"representatives. <br> <br> This is unacceptable considering that the competition is intense.<br> <br> What other avenues can I exploit to make my misery (day light *******) disappear?<br> <br> Do you think cancelling my debit order would assist?"""
