MTN Suspends account even after payment was done

This is the 3rd time that MTN has suspended my account, after payment was made ahead of time - a week before the service is suspended. Even though the proof of payment is sent to MTN, and I get a receipt acknowledging that they have received the proof. Regardless of not even receiving invoices or statements, ever.<br> <br> Trying to get hold of anyone in their call centre is a nightmare, I've been holding for 30 minutes and no one is ever available!! <br> <br> MTN, your service and network is absolutely ****! This is ridiculous!! How the hell do you run a company like this, especially being in the service industry?!!!!! <br> <br> Provide a ****** service to your customers who pay you!<br> <br> I've been with MTN for years, and I can say that they are the worst service provider in South Africa. Can't wait to change to a different provider.
