Cancellation of cellphone contract.

After 24 months on a contract with MTN, since December 2014, I have been attempting to cancel / migrate my account to prepaid. I have 3 contracts.<br> <br> Contracts are opened efficiently instore, but cannot be cancelled there. In order to cancel a contract you must phone a number ( *** ) which in my experience is never manned. The recording talks about high call volumes.<br> <br> I thought I would be clever and phone late on a Friday evening, the recording still talking about high call volumes, and after being cut off about 10 times was extremely upset. I went in to an MTN outlet and was told that the call centre does not operate after hours on a weekend.<br> <br> I was wasting my airtime in an attempt to reach their elusive call centre. The <br> recording does not notify the customer that the call centre is closed on weekends.<br> <br> I would appreciate assistance with this matter.<br> <br> Regards<br> <br> Craig
