Non-attendance to Customers and late response

I have been calling MTN for the last 2 month but no avail. Just last week I found myself staying on the line and there was no response that is when I gave up. I went to the MTN store in sandton in order to payup and I was informed that they do not accept payment so I had to go to the bank.<br> <br> I paid their money and now I cannot confirm if payment was received or not. This is totally unacceptable especially for a company of MTN's stature. <br> <br> I need to know how much I owe, and please answer your phones. This is irritating.
