Pathetic customer service

To actually say that I am irate is an understatement right now. On the 27th March 2015 I gave in my Samsung tablet 5/S (whichever it is) to the Samsung outlet at Dion Wired in Boksburg.They subsequently send the phones to Power Care who is the official service providers for Samsung devices. The long nd short of it is that while my device was in the care of Power Care it was subsequently ****** from them. A fact that I only found out after I called for a second time (the first agent Ruth **** and said it was with the agent knowing full well that it may have been ******). Power care has had a flippant customer care attitude towards me from the get go making this whole situation seem like it is my problem. They clearly do not believe in not inconveniencing the customer. What makes things even worse is that I have cc'd Samsung itself in every mail as well as called to complain about the service I have been getting from a service center that is supposed to be representing them and they do not care and say that Power care needs to sort it out. They are not even talking about any type of compensation for anything. I don't know how you guys win service awards because you suck at it.
