Querying the same issues every month

This is the second consecutive month that I've had to query a payment that was debted on time, last month I had to call the call center because they suspended my service after they "cannot find the payment," this month I had to call the call center twice because again they cannot find the payment and felt it was appropriate to suspend service both times instead of calling me and verifying the payment. I have 2 gigs of data I can't use because no one knows why. I have vented my frustrations with mtn to people and they too have experienced the same issues, something is going on with their systems and they aren't bothered to disclose it to us as their clients, I am so frustrated that if this happens again next month I am taking it to the consumer protection board!
