Unhappy customer.

I bought my wedding ring end of February 2023 my wedding was on the 11th of March by the 20th of March the stones were already falling out I took it back to the store since it was still under warranty n the sales assistant said the stones fall out because the ring is loose and advised that it gets resized.do I did that so basically I was supposed to be charged for resizing only but I got for resizing and repair.when I went for collection on the 1st of June we noticed the over charge n they promised to call me on Wednesday the 5th of June till today I'm still waiting for their call.and to my surprise the stone are still falling out again so I don't want this ring anymore and so disappointed with the service I got.and I was told if the ring was resized you can't return it,well that's not my problem cause clearly the staff members don't know what they doing.so at this moment I don't see myself trusting anything from sterns.(sterns the groove mall).
