Coverage Complaint Service

At the start of 2016 I moved into a new apartment in Lonehill, Sandton. According to MTN's coverage map this area has full LTE and 3G coverage, but I am barely able to maintain a stable 2G connection for both data and voice. I filled in the coverage complaint form provided on the MTN site and received a reply within a week. I was told that my case will be attended to, after which I waited for 3 weeks without anyone contacting me. I then contacted customer care and provided the case number for my complaint. Again I was told that someone will be assigned to my case and that I will be contacted shortly. Another three weeks passed without any assistance with my issue. I have now had this problem for more that two months, contacted customer service numerous times and have received no help.<br> <br> My contract is due for an upgrade in a few months and as things stand now I would be a fool for staying with MTN as I will not be able to properly use the service and they do not appear to be making any attempt at fixing it.<br> <br> This is the WORST customer service I have ever experienced and I am very disappointed.
