mtn contract cancellation (lack thereof)

<p>In April i notified mtn via the self service portal not to renew my contract which was due to expire on 21 April. After i have submitted my request i received a call from the mtn retension centre wanted me to upgrade, i advised to call centre agent not to renew my contract on expiry but to cancel.</p> <p>To date my contract has not been cancelled and Mtn is unable to assist due to me not having a reference number. </p> <p>Surely some useless person at mtn must check the online mtn self service portal as my request can not have vanished.</p>
