Apphauling service

I lodged a complaint with MTN on HelloPeter on the 17th of November after many years of begging and pleading for them to do something about the bad coverage in my area. I received a response from a gentleman by the name of Tim, stating that he would give me feedback, as soon as they get feedback on the escalation done. I have not received any feedback. I can still not have a conversation without the call being dropped, I still cannot open the gate for my visitors in the complex as my phone doesn't ring and I couldn't even finish the conversation with a gentleman at MTN's Network Group to request feedback, as the call was dropped before he could assist. He did however have my number and did not call me back.<br> My phone bill has been a couple of thousand rand a month, most of it being data. I switched off my Cellular Data, but still the phone bill went up. I requested an investigation, and never received any feedback. Called again today and was told that the query was closed.<br> I am now lodging a formal complaint with the National Consumer Tribunal. I refuse to continue paying for a service that I am not getting and haven't received for years.
