Service complaint

I called to do a simple thing which is changing my debit order date. MTN failed to send me a debi check for the new debit order date and therefore did not deduct the premium on the agreed date. Today they sent me an email saying they have stopped my service because of non payment😡

I called them to make alternative arrangements to pay and they said they will deduct the amount in the morning, i gave consent, however the money still hasn’t been deducted. They also promised to send the debi check which still has not been done.

I had to call them back again to tell them the same thing, which is that they should send me the debi check, now they are saying i should call back later. The service i have got i trash and i have to be the one running after them as if I didn’t tell them on time about the new debit date.
