Stones coming off

I have 4 pairs of earrings I bought from Swarovski,and 2 watches , I bought some overseas and some local. Two of the earring which both have 1 big stone,like pea size stone. The stones came off. When it happened to the first pair I took it to my nearest Swarovski,thinking they could fix the problem even if they charged for it would have been better,but I was told they do not fix. I was disappointed. And the second earring the stone came off,I was like something is not right here,2 of their products with the same issue not even after 10 years,whereas I do have cheap jewelery than theirs, with stones, but I have never had a problem with those. From then on I told myself I will never buy anything there. The watch story is different ,it fell and the winding thing got bent ,they were unable to fix that and was told to take it to other jewelry stores . Was shocked by that. Honestly I don’t think I will ever buy there again.
