UNABLE TO CANCEL CONTRACT

My 24 month contract is due to expire at the end of May 2015. As per MTN's requirements, 30 days before the end of contract i attempted to give notice to cancel my contract (30/04/2015). Over the space of a week i spent 2.5 hours on hold trying to get through to a consultant at the call centre! After losing 2.5 hours of my life i sent an email to [Email Removed] I waited the standard 5 days and received no feedback, not even an automated response to the email. Today (19/05/2015) I attempted to get through to the call center AGAIN and gave up after a half hour on hold. Its been almost three weeks following my email and STILL NOTHING!<br> <br> Am i now expected to pay for yet another month simply because MTN has such poor customer service? Can someone please assist me in cancelling this contract? Come on MTN, prove me wrong.<br> <br>
