MTN Complaint, again.. nothing unusual.

I see so many complaints about MTN services, and yet nothing has changed.<br> My contract has expired with MTN and i went in about 2 months ago to cancel. So they said they would.<br> Nothing happened, I went in last month to make sure it was cancelled and unsurprisingly it was not cancelled.<br> They said i was behind on payment in which i paid R500 odd rand for on the spot. The lady claimed it will be cancelled with immediate affect.<br> WHAT A SURPRISE!!! still not cancelled. Now they have given me data for the month and obviously i have not made payment, so my sim has been locked. Phoned MTN, now they tell me i need to pay and use my data up and phone again at the end of the month to cancel.<br> <br> WHAT MUST I DO??? SHALL I BEG AND PLEAD TO CANCEL SOMETHING I NO LONGER WANT???<br>
