MTN worst service ever!!!!

We app**** for 7 contracts! After porting the wrong number (a fault on MTN's side) they bill us almost R4 000 for the cancellation of the wrong number!!! Then 5 of the 7 numbers did not work after 2 months. The reason: RICA problems. We then did RICA the numbers again. Still not working. The next excuse: somebody cancelled our contracts. I asked who? Nobody can tell me. There is no reference number or name for the cancellations. The we had to write a letter to state that we did not cancel the contracts. The promise: will be re-activated within 2 hours. And yet here we are, 24 hours later (actually 120 from the first complaint) still no phones working! What will be the next excuse MTN? This is totally unacceptable. We need these phone to help safe guard children in the afternoons. Thanks MTN for not helping keeping our children safe.
