MTN SERVICE NOT UP TO STANDARD

We have been with MTN for many years and their service has steadily declined from excellent to a point of almost no service at all. We pay a monthly fee per line for a service to have telephonic communication anywhere within South Africa but during load shedding we have no service at all not even emergency calls. Since we are paying for full service we expect just that. I tried to call MTN business customer service line but the line was so bad, breaking up and eventually the call dropped on its own hence this complaint. Taking the crime statistics into account my concern is that should we have an emergency of any kind that causes us to need urgent assistance during load shedding we are totally isolated because MTN does not make provision for load shedding to keep their towers operational. Even when load shedding is over and our phones indicate full signal strength our calls frequently breaki up and drop irrespective of where we are. We in Crystal Park literally have service and signal for about 12 hours out of 24. This is TOTALLY UNACCEPTABLE AS WE ARE PAYNG FOR 24/7 SERVICE. IF WE DEDUCT THE AMOUNT FROM OUR ACCOUNT AND ONLY PAY FOR THE TIMES WE HAD SERVICE MTN WILL JUST SUSPEND OUR LINES UNTIL WE PAY THE DEDUCTED AMOUNT. FOR THIS VERY REASON WITH MTN EXPECTING FULL PAYMENT WE EXPECT 100% CLEAR FULL SIGNAL 24 HOURS A DAY SEVEN DAYS A WEEK IRRESPECTIVE OF LOAD SHEDDING. We chose MTN to be our service provider as at the time they were deemed to be the best by far but it seems they started to lose their customer service commitment to the point where tower down time is of no concern to them. SHAME ON YOU MTN FOR ALLOWING YOUR CUSTOMER SERVICE TO DECLINE TO A POINT WHERE WE FIND NO OPTION BUT TO WRITE A COMPLAINT SUCH AS THIS I
