Bad customer service and no staff communication

I handed my Samsung Tab in at the Eastgate Branch for repairs. I was told that I would have to pay R180 assessment fee if they were unable to fix the device. Over the course of a month I received so many phone calls from so many different people saying different things, that I could not keep head or tail. One call said that the device had been repaired and I could come collect it. Then I was told that it was not repaired and needed a master reset, would I be OK to lose all the data, to which I gave my go ahead. I received yet another call a week later to ask my permission for the very same thing, which irritated me as I had already said they should go ahead. I then received a message last Friday to say that they could not repair the unit and I best come and fetch my device by month end as they were moving away from Eastgate. I went in to collect my device yesterday and was handed the slip to sign as acceptance of collection. There were so many hand written notes on this document that I am not suprised that they had no idea of what had actually been done on my unit. Now I discover my screen protector was removed and not replaced! Unacceptable. I am not impressed at all!
