Do you have an account with Kay Jewelers? If so, it's from there collection dept. I know, because i have gotten them at home and that's one of the numbers and names they use. Good luck!
They're annoying as hell. I have no account with Kay Jewelers and never have. They keep calling for someone I've never heard of and doesn't live here and I've told them at least twice, I don't know this person but I still get calls.
