I purchase Tiffany bracelet s few years ago that I can't even wear.. I have lost it twice and luckily found it both times very sentimental…I've taken it bk to both the Beverly Hills store and Woodland Hills to have links tightened it came off again . I'm 65 yrs old n it's not like I'm partying just simply wear it .I took to a jeweler they said it's a defect in clamps .I loved my bracelet and feel it's is Tiffany's responsibility to correct this problem I have a bracelet I can't even wear. Please help
