MTN empty promises!!!!!

I have had a problem with MTN coverage for over 2 years now.After numerous calls and complaints,I had a call on the beginning of 2017.The gentleman promised me that they are looking into the problem,as we are not the only MTN customers that complained about signal,coverage and drop calls in our area.On Friday somebody had to call me back 6 times because during every call we got disconnected.I use about 8GIG of data a month,and this is only for residential use alone.I have 3 data contracts with MTN which I pay over a R1000 a month for,and still all of their promises ended up EMPTY!!!!!Sometimes I think this is a way of making money out of the customer.When my contracts expire I will most definitely not upgrate on MTN again,and thats my PROMISE.
