Empty promises

I have had a tablet for about 13months, no problems everything was fine the battery died on me as is what happens when you don't keep it charged. Anyway I haven't used it in a while. Last week I charged it and wanted to use it and wouldn't accept my pin, I tried again no such luck. I went to my home branch in Westgate spoke to a guy by the name of Adrian after about 1 hour he discovers my sim card was NEVER registered. He gives me back my tablet and says he is off tomorrow ( Wednesday) but he has to come in in the afternoon and he promises he will call me with the pin. Wednesday came and went I thought maybe he didn't come in as it was his day off I will give him until tomorrow (Thursday) guess what it is a week later I still have not heard from him. Yes I have called and he was not in I have left a message for him but nothing. On Saturday I will be going elsewhere. Every time I have upgraded I have a problem of some sort or the other, this is the last problem that I will have from Vodacom Westgate. The best shop for bad business.
