Wrong ring size adjustments

18March2025 I bought a ring at Centurion Mall American Swiss that costed me over 10k.i found a store consultant there. Told her it's my first time purchasing a ring so I am unsure of ring sizes. She said to me don't worry I will assist you with that regard. I chose a ring then she fitted me and advised to take L or K size since my fingers are very small. She then told me to pay an extra fee to resize the ring. I had no problem with that. Yesterday 24March2025 I went to collect my ring as it was back from resizing I fitted it and surprisingly it was still very loose, it spins around my finger while I'm wearing it goes in and out like it will fall off. I found a kind consultant who was assisting me she measured me and said the is noooo way you can be a size L. She fitted me to be a size J1/2 If I still remember and indeed it was a perfect size for me. I then asked them to resize it and she went to call her manager. The manager who then explained that their policy doesn't allow them to change a ring size 4 sizes up that all rings come in a universal size N and they can't resize it beyond a certain limit. I told her this clause was never explained to me or my husband because if I knew I would have never perchased the ring at all I'd have opted for a custom made ring as now the is nothing much they can do to fix it. Any fixing I have to pay additional costs for it. And my big question is are store assistants hired without any training or whatsoever. As a customer I believe they are the face of American Swiss and assist customers with knowledge and expertise. Why is it my problem that I took advise from the store consultant and now it's my fault that the ring doesn't fit. Is it her first time dealing with clients with small fingers. If unsure she could have asked for a second opinion from her colleagues. I'M BEYOND DISAPPOINTED AT THE SERVICE I RECEIVED AT AMERICAN SWISS, Centurion Mall. In their defance they claimed that maybe my fingers were swelled up which can never be true. I dont struggle from such a condition at all. Explain to me HOW ALL THIS IS THE CLIENTS FAULT? WHY AM I TO BE HELD LIABLE FOR STAFF INCOMPETENCE?
