Pathetic after sales service Galaxy GEAR 2

I received a Gear 2 smart watch in August 2014 and used it a few times at the gym to stream music to Bluetooth headphones whilst cycling. In January 2015 it stopped charging and I noticed that one of the contacts had completely eroded. I took it to the Boksburg repair centre (Darro Electronics) on 3 February 2015 and was told that it wasn't covered under product warranty as the fault is due to mechanical failure! I discussed the matter with the Darro Manager and requested that they book it in and take it up with Samsung as this was clearly a design problem. A colleague of mine had exactly the same problem with his Gear 2 and we booked both watches in at the same time. Despite many phone calls, we have not had any feedback from Darro and promises to call me back have not been kept. I contacted Samsung Head Office on 27 February and asked to speak to a client service manager (Sylvester) but was told he would call me back. I phoned again on March 3rd, and was again promised a call back. Its been a month now since handing in the watches with no feedback or status update whatsoever. It appears as if this fault with the Gear 2 is an \elephant in the room"...."""
