BEING OVERCHARGED FOR DATA THAT I AM NOT USING?

I have had an ongoing dispute with MTN from end Apr (which still needs to be resolved and I have not heard one freak-en word from MTN) and again 12 May regarding the ongoing investigation and Credit to be passed as per reference number 127 553 953 for being crazy overcharged for so called data that I am not even using as my phone data is switch off and I use WIFI.<br> I have made so many calls to 808 & send emails to MTN call centre with no results. I have asked many times to rectify the issue and it is still ongoing. WHAT IS GOING ON!!! why does one have to beg for service???<br> Also still waiting for follow-up on a query I submitted last month after I also received a increased bill due to so called datacharges. MTN made me think is was due to my fault & it started just after the LTE upgrade , however in after Balise (the customer care consultant I spoke to during the conversation of the 12/05) mentioned that I was being incorrectly charged data usage & can clearly see it is the same issue. I can see on Hello Peter that many people are being ripped of by MTN in the same way. To get hold of anyone to assist a person is like pulling a chickens tooth...non existent. HELP!!!!!
