Bad Service

I have made several attempts at cancelling my contract. I must have spent 90 minutes in total waiting for the call centre to either put me through to the cancellations department or simply dropping my call after 20 minutes. I have been greatly disappointed with the service both in stores who seem incapable of dealing with this and a number of other issues thought my contract the last 2 years. <br> <br> On top of it all I was advised on a contract, which later turns out to be totally intractable not being to upgrade or down-grade. Not being able to get roaming data, travelling international. Not to mention the poor reception and call quality both where I work and when I travel to Nigeria.<br> <br> I have a great amount of money in credit on this My750TopUp Contract which I am sure I am going to lose, as I have been told that the money cannot be transferred or converted in any way. This is simply unacceptable.<br> <br> MTN, contact me so I can end this contract once and for all.<br>
