Refuse to honor Warranty

Over the years I have bought many items of jewelry from Swarovski. I find that the metal plating comes off very quickly, and when I complained I was told that I have not been looking after it. Nevertheless, I still continued buying their jewelry and taking better care of it, but my last ring that I tried to take care of, the stones started falling out. I went to the store where I bought it and showed them, they said I must go look for my warranty. I went home and found it and went back, they took a picture of the ring & warranty and said they would call me. Two days later they called me to tell me that they can't help me cause I waited too long to come to them & too many stones have fallen out by now. The warranty is suppose to be for 2 years, I bought the ring last year June.
