My sister got a call from this number stating they were from RDAC or something like that, by the name of Lynn Walker. She did mention "patient" or something like that. I'm kind of hesitant to call them back, but I don't want my sister to keep receiving these calls, not do I.

I received a call from this phone number 615-690-1687 to my cell phone for a person that was not me!

I received a call from this number 615-690-1687 (linda walker) on my cell phone for someone else, not me. I ask her not to call my cell. still call once a week. this is a debt collector looking for someone else.
