Worst experience!!!

I ordered a device and plan and also requested to have my number ported from Telkom to the new MTN contract number. I received my new device and found that it was the wrong phone and that my number was not ported. I was then advised to buy a MTN prepaid sim so I can port my number from Telkom prepaid to MTN prepaid and once was done do a number swap onto the contract sim. I did all of this but then realized the plan they gave me was incorrect costing me double the premium I signed up for. I then requested them to change the plan to what i signed up for and they advised its not possible and I have to cancel everything and then sign up again. I was also told that the plan would only be cancelled once the device is returned. At this point my phone all of a sudden could not receive calls could receive or send SMS's either. I retuned it at MTN century City on the 21st Jan and have been phoning daily to check up on it. Till today no one can give me any proper information about where the phone is and also their call routing service is faulty as I cant seem to get through to the relevant department no matter who transfers me which is really annoying! I am also being billed for my contract which isn't cancelled due their delay in getting the device to the right place to be checked out and cleared.

Really really really bad experience!
