Poor service or no service by MTN

I would like to know why we pay for services rendered by MTN? I have 4 contracts and one pay as you go in one household, not in the last three to four weeks there is hardly ever a signal. When reporting this to my local MTN outlet they themselves said that they could not complain or put in a complaint for me as they where also offline. What does that constitute for us paying for a service and not getting any is my or other users experiencing the same problem. Loadshedding cannot be blamed as sometimes there is still signal for a short while after loadshedding begins, and on other occasions loadshedding ends and takes up to an hour to MAYBE get signal again. I am an ex telecommunications technician myself so know that this can be sorted out with skilled workers. With technology if one tower goes down the signal should be able to be re-routed through another tower. KINDLY ASVISE MYSELF AND OTHER USERS IF YOU ARE NO LONGER ABLE TO RENDER A RELIABLE SERVICE OR NOT. I have no way of communication in the event of an emergency having a person in the household suffering from mental illness so find this most distasteful that I dont recieve the services I am paying for. Please MTN sort out your problems or technical staff, wherever the problem might be!
