Refund request

Dear mtn<br> <br> I requested my contract to be cancelled for the number *** the 2 April 2015 via email which was more than 30 days in advance as per terms & conditions however I have received no reply from your email department. I then sent 3 more email & still no reply & I still have those emails on my phone as proof. I then called into your call centre 3 times & I eventually management to speak to a team leader by the name of Vergina reference for the call *** who assured me that my contract was cancelled & my last payment was in May however there was amount debited from my bank account on the 30 June of R513 which is also more than my contract amount as well. I would this amount to be refunded to me as I have notified you more than 30 days in advance to cancel my contract & it is not my fault that your email department has not rep**** to any of my emails. Plus I cannot get through to the call centre because my call everytime gets disconnected.
