Bad service provider

Is everyone at MTN ***********? When I phoned previously they said my account is on a debit order, apparently it isn't as my line hot disconnected on 03/11, I made a payment early in the morning and called for mtn to reconnect my line, they did it, on 05/11 it got disconnected again, I called again for them to reconnect my line and they did, on 07/11 it got disconnected again, I called 135 and asked to speak to a supervisor, and she told me that there is no supervisor on weekends, but she apparently reconnected my line eventually, I restarted my device and still it was not working, then called again then the lady said she needs a valid reason for me to speak to a supervisor, which I told her and the phone line got cut (hang up), I phoned again and asked to speak to a supervisor and obviously I was furious at this time, she said she will get them after I explained why, then she got back and said "the manager is too busy to speak to me" she agreed to reconnect my line and I had to reset my device, I did but till now it is still not reconnected.
