Waiting and Waiting

In December, we returned a ring as one of the stones was discolored. It has now been 3 months since we have handed it in. Firstly, we don't receive any feedback about the ring. Secondly and subsequently, we are now being told that the ring just arrived back but the problem was not fixed (basically, I don't think that anything was done this whole time!!) Thirdly, the staff at the Hatfield branch are actually *********** in all ways in assisting a customer in all manners and matters. This is really just getting out of hand now and i would like this sorted out quickly!
