MTN poor service

I have been trying to cancel my MTN contract for the past 3 months. After finally getting a cancellation fee amount I promptly transferred the money to their nominated account with the reference they required. This was over two months ago. Every time I phone them to finalise the cancellation, the operator tells me that a retentions consultant will phone me within 48 hours. According to MTN there is no other way, I have to wait for them to phone me. Well I have been waiting for 8 weeks now, congratulations MTN this is officially the worst service I have ever received from any provider (and that is saying a lot). Now when I phone the 808 call centre to, ONCE AGAIN, attempt to cancel my contract, I wait for 5 minutes and then the call is cancelled. MTN has been sitting with my money (cancellation fee) for the last two months and have made no attempt to cancel my contract, to the contrary I have had to pay another two months of subscription fees. From where I am standing, this is looking a lot like THEFT.
