ONCE AGAIN MTN

Hi Good day

I am really getting to the point where I am fed up with MTN. I have been paying my MTN accounts cash every month with no problem. From Friday 16th November I have not been able to receive whatssapp and internet. I phoned mtn this morning my line has been cut due to no payment I MADE PAYMENT last month. But they cut my line. I phoned this morning they tell me because I pay cash that I need to make payment arrangements every month cause I only get paid on the 2th of each month. I have never had a problem why now all of a sudden. I don’t have time to phone every month and why is this an issue now? I have always paid my account and now this. When I asked to put me back on debit they wana charge me double cause MTN bills in arrears. What nonsense is this. I mean really what next. Pls sort this out as I don’t have time for this and all my inconvienace. I need a phone as my child is in day care I need correspondence every day. I cannot have this problem with MTN.
