CONTRACT OUT OF TERM, MTN WON'T CANCEL

On 30/12/2015 I called MTN to cancel 2 contracts which are both out of term. I can neither afford nor do I need these contracts.<br> Refer reference numbers: *** & ***. I was told that it could take up to 4 days. In the mean time I received an email trying to convince me not to cancel to which I responded that I have to cancel. I heard nothing back from that email.<br> The account then 'turned over' to a new month on 20/01/2016 and new data and airtime was allocated. I called your call centre (808) again on Friday, 22/01/2016 to escalate this issue. I dealt with a manager by the name of Mr Mohlammed - reference number: ***. He said that he was emailing the retentions department to clear the matter up and that it would either be cancelled later that same day or by Monday. He said that I would receive an SMS or a phone call to confirm this. Well, it is now 20:30 on Monday, no sms, no phone call and an account which is NOT rightfully for me to pay has just arrived in my inbox! I specifically cancelled in December 2015 so as to avoid having to pay for something that I don't need.<br> Please clear this up and credit the new account.
