Bad Quality and Poor Service

I purchased my husbands wedding ring in November 2018 My husbands ring size is a Z+5 i found a stunning silver plated ring with one small diamond and gold in the middle.

To begin with they had never mentioned that they could make it to his size , they had taken the ring that was on display which was a very small size and had it re-sized to his size.

Upon receiving the ring i i noticed that there was a line on the bottom of the ring (obviously from it being re-sized)

Not even a month later the ring started to scratch and the silver was wearing off (he is not working with heavy machinery or chemicals)

The 2nd of January 2019 i took the ring back to the store and told them the problem , they then went on to tell me that it was our fault the ring was in that condition and that they could only send it to be fixed the 16th as that was when the technician would be available.

I took the ring back on on the 26th of January and they had sent it to get "fixed". I collected the ring on the 3rd of February 2019 while in the store i opened to inspect the ring to find that they had just polished the silver to get the scratches out and they landed up polishing over the diamond which now looks like a sanded down piece of plastic. There is also a chip out of the ring and the line where it was re-sized looks like its about to break there.

I am extremely unhappy with the serviced i recieved as the first time i took it back i received very poor service from the lady saying that if i didnt like it then i should just return the ring and they will give me my money back.

They should have rather informed me that when i purchased the ring they would be able to make me a new one but instead took a 5 sizes to small ring and made it bigger to fit the size needed.

I have got the ring in my possession and i am one very unhappy customer........

I would either like a refund or a brand new ring made to the size that it should be.
