FAULTY CELLPHONEI

I visited the tygervalley vodacom store last week and purchased a new cell phone cash. (vodafone smart 6) Yumna set up the phone for me ( which took 3 hours) and I left the store. In the car the bluetooth would not connect and when I tried to call a contact realised only 62 of 200 contacts were present. I then returned to the store in the cold and dark where they bluetoothed all my contacts over. I then went home again phone would not connect and at home again only 62 of 200 contacts present. I then turned off the phone and had to re-start my blackberry. I returned to Yumna at the store over the weekend and he was most irritable with me and rude that now my cell phone is not \working"and what have I done wrong!! he then tested the cellphone to find out that the cellphone is faulty. I now am sitting with a blackberry that is now operating well and a BRAND new phone I purched cash and not even on for a couple of hours has been sent in for assessment. why on earth could the phone not be replaced instore immediately???? its now a week later and still no work on my cell phone replacement. Im absolutely disgusted in the service from vodacom!!!!! please take the ad off TV!!"""
