It IS a debt collector. I answered the call after they called a couple of times, and they asked for an individual that I knew, and wanted more info on him. I told them I didn't have any, and to please take me off their call list.
This number is a telemarketer who is Phishing...they want you to call back..don't call them, and don't leave your name. They are the same "kick" as the 1234 number claiming that some credit union card that I never heard off has been canceled and I need to call them to reactivate> Don't ever trust these guys, and never return the call - delete it!
