No one to talk to.

I have been trying to get hold of MTN for 2 weeks now. No one has answered their phones and no one has returned my calls, I stand at the MTN shops for 40 minutes without anyone even acknowledging that I am there while the queue is 10 people deep.. <br> <br> I have a monthly data bundle that I want to stop. Yet the end of the month has come and gone and I cannot cancel it because there is no one to talk to. I expect someone from MTN to contact me now to cancel the data bundle and to refund me for this month.
