Cancel Contract

After switching over my Vodacom account 24 months ago to a contract with MTN, I have been attempting to cancel my MTN account and move to a prepaid, seeing that I have another prepaid account and one other contract with my work phone.<br> <br> Contracts are opened efficiently in-store, but cannot be cancelled there. In order to cancel a contract you must phone a number ( *** ) which I have a couple of times on 7 Dec (ref ***) and again on 14 Dec (ref ***) and again on 15 Dec (ref ***). They mentioned initially it will be cancelled withing 48 hours and 192 hours later and I am still awaiting my sms confirmation that it has been cancelled. <br> <br> I would appreciate assistance with this matter.<br> <br> Regards<br> Juanry
