wedding ring

Guys I'm so disappointed I had bought a wedding ring for my fiance in Feb my fiance has been complaining about the diamonds catching on her clothes and also the ring on the inside is silver which I don't like ,we had called the guy at bluff nwj to advise him bout this and he said that there are no refunds on sale items he then told us its to late to exchange i then waited for the shop to open up and I took the ring back to say I dont want the ring anymore as my fiance is not happy at all with the quality of the ring bluff nwj booked the ring and sent it to head office it took 3 weeks for Ramona to get back to us today only after me phoning so many times she had told me the ring has been assessed and they cannot give me a refund as there is no default on the ring and that I can go get a wedding bands I had told ramona I had put a deposit on a wedding ring else where so she said to me how can I go put a deposit down on a ring not knowing the outcome if nwj will refund me .firstly the way she spoke to me I dont like thats not her business and I dont feel as a customer she should address me I that way .I spoke to rashma she also advised me no refund and she will get back to me I feel as a customer I'm entitled for a refund and I don't want anything else from nwj so if u guys can look into this matter urgently .
