ABSOLUTELY DISGUSTED AT THE SERVICE AFTER BEING A CLIENT FOR 20 YRS

MTN, I have made over 80 calls to your call centre, emailed, messaged you on social media and ABSOLUTELY NO ONE CAN HELP ME. I am beyond frustrated at this point! 4 DAYS without being able to receive calls and sms's. 4 DAYS as a loss to my business and MTN does not care. Firstly my line was cut off despite paying my full account on time. When I called to reconnect services and inform MTN of the error, only a portion of the issue was rectified. I can now make calls but cannot receive a single call. I have tried every code given to me and it still does not work. It is not a new contract, my sim is not damaged, i cannot go into a store. Someone broke something remotely and they must now FIX IT. I have 3 lines associated to this contract and ALL have been affected. This is now messing with my income, my livelihood. I have been a LOYAL customer for 20 YEARS! MTN, WAKE UP, YOUR SERVICE LEVELS SUCK! I AM BEYOND ANGRY RIGHT NOW. I held on for 45 minutes at one stage for a consultant to then cut me off. How is that acceptable?
