Shocking signal COMPLAINT no 3!

I first submitted a complaint in early September of this year. In the 3km is takes to drive to my office I will have four dropped calls due to appalling signal. At my office people are unable to use their phones indoors (even on the top floors). I received a list of information that would be required including details of other people suffering the same issues, which I supp**** to MTN. <br> <br> I have received no further feedback since my second report on Hello Peter when they assured me the complaint had been sent through to escalations. I am also not entirely sure what reference I should be using??<br> <br> 1. Coverage query logged with reference number ***<br> 2. REQ:***<br> <br> I am paying for a service I do not receive, this surely cannot be just, fair or indeed legal. I am also held to ransom as I cannot change providers mid contract without settling with MTN.<br> <br>
