Signal problems since Apr 2014 still unresolved

We have struggled with mtn since April 2014. Nothing has improved about the signal in our area. We cannot make or receive calls from our home or our factory unless we drive a couple of kilometers away. <br> <br> We are still paying almost a R1,000 for 2 Autopage-MTN contracts every month which are only good for receiving messages (and even messages get lost). We have to divert our mtn numbers to Vodacom prepaid to be able to make and receive calls. So we each have to carry 2 phones around.<br> <br> Despite numerous visits and calls from mtn staff, nothing has been resolved and nothing improved. Each time we complain, somebody new takes up the matter, and then it fizzles out and nothing happens, till we again complain and the same nothing is just repeated. All Autopage's correspondence with you it also achieved zero.<br> <br> The booster you installed in August at our home was supposed to enable us to at least make or receive calls whilst inside our home, but that worked so-so for less than a week. We keep on sending mtn emails, and get read receipts but nothing else
