mtn - nowhere YOU GO

I have cancelled my contract several weeks ago in July or August and paid any outstanding amounts at one of their West Rand stores. I was very clear that I wished to switch and be only on Pay As You Go. I then bought some airtime. Lo and behold I am now cut off for non-pament. Is there any business in this country that knows what they are oing or even cares. If I call customer service I am told that Its not paid and not cancelled I am not a millionair and I don't know how many times I must pay the same amounts over and over for their mistakes and even get handed over. It is the most bizarre thing..Luckily I emigrate soon... The service in this country really SUCKS!!!!!!!!!!!
