Game Westgate Cellular dept- Bad service

I am completely disgusted at the service I have received from the Cellular dept at Game Westgate in Gauteng. I went to do my contract upgrade there in the beginning of Aug. I firstly experienced issues because the staff member who assisted me, Bongi, provided a deal which needed some code which was not available. It took them 3-4 days to get that sorted after me having to call and constanly follow-up and go to the shop to perform because I was not getting feedback. Eventually, I collected the devices but no sim cards were available. I was told that I will be contacted when the sims are ready. It is a month later and nobody contacted me. I called on 02/09 to enquire and was told by Bongi that Vodacom had not registered the sims yet and he would contact me by Monday the latest. Once again, I was not contacted and I have to waste my valuable time and money to constantly have to call back to get some kind of feedback. Yesterday, 05/09, I called again and was told Bongi was not available and the manager, Brenda, promised me that she will advise him first thing this morning to get it sorted and contact me. Surprise, surprise....I am still waiting to be contacted. This is utterly ridiculous!!!!! Please do something about this.
