Shocking Service

My husband bought me a Guess necklace for Christmas, when he got home he realised it was damaged. He couldn't take it back as I then wouldn't have it as a gift on Christmas day. I took it back on 30th Dec and was advised they would send it off for repairs. On 03rd Feb I had still heard nothing so I called. They advised the warehouse only opened 2 weeks into Jan so it was still there. Someone called me on 16th Feb to say that I could collect my necklace and they had replaced it with a new one. I went to collect it on 20th Feb and they had sent a bracelet instead! I expressed to the kiosk clerk how disappointed I was and that someone should get back to me to advise what is happening. By 24th Feb I had still heard nothing so again called and spoke to Ashley, I was very upset with their customer service which I expressed and she said nothing until I told her she should be apologising! She then advised me her supplier no longer has stock of the particular necklace and would replace it with an alternative of which she would send me pictures, she was just waiting for the email from the supplier. I still have nothing! The lack of communication and service is shocking!
