MTN Online Upgrade Horrible Service

I have started the upgrade procedure on the 28/09. Once finished with the hour + session I realized the sale rep had added the wrong package when comparing prices to there booklets I phoned back within in hour to amend the upgrade and was told they can no longer assist me as they have already placed the order and I must now wait for DSV to phone me for delivery and tell them to cancel it - Why I must advise a 3rd party of my cancellation in the 1ste place is beyond me. DSV has phone me on the 2nd and 5th on which I comp**** as per MTN's sales department Now at this week I am still not being assisted by MTN - just being either transfered between departments or just being hanged up on. Total time spent listing to their hold music and repeating the security questions @ 4 hours and 47m and still no further than I have been 13 days ago and tomorrow I become liable for a contract (as out of cooloff period) with no phone and a contract that I have been trying to stop for two weeks...
