Poor service

CellC have a buy out special from other networks. After finding out what the procedure is and how to go about it, I was encouraged to action it. This all being done was only told subsequently that they had no device in stock. However there was one in Kenilworth which would be there the following day, once it arrived CellC would call. 3-4 days later with no call, decided to make another trip to the store. Only to find that the wrong device was ordered. I was then told that the correct device (64G black iPhone) would be there in a week and this time for certain they would call to advise either way. To my disappointment again a week later, no call and on a further visit to the store, no device. This has all left me wondering why I left Vodacom in the first place
