I'm pretty sure this is a debt collector. I get  calls from numerous debt collectors and schools asking for the same person this guy was looking for. I didn't ask, I don't really care. I just wish they'd all stop calling.

i don't know who keeps calling me from this phone number. they've asked for my social, name, number, address but wont tell me who they are

They call from 3 different numbers. I think they are debt collectors or scammers who want into and don't leave messages, but call several times a day. They show up as "California" on my caller ID.
