Bad service

My husband purchased our wedding rings in October 2022 ,we received the rings in November due to the fact that the rings needed to be resized December .We went back cause the rings had marks where it was resized, they informed us the workshop is closed due the season. We went back on 16 January , the rings went in ,we received the rings say two weeks after that again March it made the exact same thing so it went in again, they called me and said the workshop is saying if it does the same thing they won't take it back again, so I logged a complaint with head office they say they can't refund or give us new rings cause it's our fault. I've never experienced such bad service in my entire life.It is our wedding rings and it has sentimental value.
