Putrid Service from Vodacom

I upgraded online and a few days later called in to cancel the order as i saw a deal , still with Vodacom but with the 4U branch .The device i wanted from 4U needed to be ordered , so i waited for it but i just had a gut feel and a wek later i phoned again to check that the online upgrade was cancelled , since i would not be able to take the 4U device if the other upgrade was still there . I was told it was ever cancelled and a call needed to be logged .The call was logged , but closed the very next day without anyone giving me a call , which is what i was told by the agent.I then phoned another week later , since the 4U device was there and i though i would just phone before I drive to the shop and arrive and here the quote is still there .And as i thougt , the quote is still there .The device is now at 4U , but i cant go collect , becaause the quote is still live.When i phoned yesterday i was told that someone from quote reversals would call me and to date , no call .I have had to call Vodacom myself on 4 different occasions to get an update from the right department ......the only time a get a call back is when i phone 135 and the call drops , but when i have an actual quesry ....there is just a black hole , where the query goes into and no one calls back ???
