The caller ID said SIGNET, which ther are several references as to who it could be. One of which was SIGNET jewelry. This I believe is what it could be since I have been getting a rash of these calls - Srerling, Kay, Jared, etc. the phone number keeps changing. I do not have an account, I don't go to jewelry stores. This is starting to get old with approximately 5 calls a day. I block them and then the numer changes.
