2 missed calls a few days apart, tried to call back a few times but went to voicemail and I got through today and they didn't seem to have any idea who I was.

They asked who I was and I replied with my name and then they asked where I was from.
I'm not a business, and I don't know why they would ask where I was from?

I asked if there was anyone else there that may have called me, they said there were a few others there but weren't aware of anyone else using the phone (they also did not ask anyone if they had made phone calls). The number had called me not even 2 minutes beforehand.

Seemed to be a private residence as I could hear TV in the background.

Very unusual.
