Incorrect billing

I received an invoice in January 2016 for my data card ***) for an amount of R2756.24. <br> <br> The normal monthly instalments since day one was R78.00 per month. I have logged numerous calls on the website and received a response that I have to submit a letter authorizing Autopage and MTN to investigate which websites have been visited and what data was downloaded. And then the query was closed. <br> <br> I yet again forwarded a complaint, got another ticket and this time received a response that the matter was handed over to the accounts department. And guess what - yes nothing happened. I logged numerous complaints all get closed without a response.<br> <br> What these idiots don't understand is that me and my family was in the UAE in Decemebr and the data card was locked away in my safe at home. So it all boils down to theft - probably to finance there closure!<br>
