MTN refusing to allow contract cancellation

I am posting this for the third time as I am yet to receive feedback since my last post. REQ ***. Please have someone contact me today on ***. <br> <br> I appalled at the way MTN are handelling my request to cancel my contract. I have yet to receive a response from the mail that was sent on 22 April. ***. I have called the call centre numerous times and have only managed to get through once where I was promised a call back that same day as the retentions department was apparently not taking calls. I am leaving the country and I need to have this resolved immediately!<br> <br>
