Bad service @ American Swiss Greenstone.

My engagement ring was slightly bended on the one side so we took it to the American Swiss where we originally had bought it for repairs. I gave the ring in on Sunday 10th of April 2016. I was told to wait 5 to 7 working days for a quote. On Friday, the 15th of April I had to phone them for feedback as i never received a call from them. The lady told me the price of the repairs and I nearly had a heart attack. Thinking of the minor damage on the ring and the price to repair it, was just unreasonable but however decided to give the go ahead for the repairs. On Monday the 18th of April they phoned my fiance to say they never received feedback as to whether they should go ahead with the repairs. He gave them the go ahead on Monday again as I already gave the go ahead on Friday. The lady said again the repairs will take 5 to 7 working days. I phoned them again on Friday the 22nd of April as again I have received no call from them. Only to find out that my ring was never booked in for repairs as the lady said to me she never received any feedback from us to go ahead with the quote, but they spoke to me and my fiance and we both gave the go ahead. Then she wanted to use the excuse that the ring was badly damaged that is why it is not ready. There is absolutely no communication between the ladies working there and this will be the 3rd week without my ring. I am very unhappy about the servive and the way the staff lie to the customers to cover up their own mistakes! They are realy inconveinincing me and the fact that i have to phone them every time is unacceptable!
