MTN UPGRADES

I am a loyal MTN customer who has recently had a really bad experience. I was contacted by Velocity PTY Ltd (subcontracted to MTN for upgrades) in April 2015 regarding my cellphone upgrade. <br> <br> Firstly my request was not processed for two weeks. Then MTN went on strike and subsequently I have been unable to CANCEL my request despite numerous calls. I call Velocity on a regular basis and get told that someone will contact me in 48 hrs.<br> <br> My request for a cellphone update precedes the strike. I have still not received my upgrade. MTN refuses to cancel the order and requested that I contact Velocity PTY Ltd . I have called Velocity on a number of occasions and they have not cancelled the order hence 5 months later I am left without a new phone and both Velocity/MTN refuses to help!!!! All I want is for the previous order to be cancelled so that I can request another 2 year contract with MTN...this is bad service. Why in the world am I having to sort this out with Velocity when MTN is my service provider
