received 6 calls from Mike Anderson from this number, he started harassing me at work, when I return his call a different person said would help me, he started saying I have a judgment against me and started reading the judgment to me, he put me on hold because someone in the background was screaming and being rude to a person on the phone demanding payment, I asked the individual to please fax me a copy of the judgment and he refuse to. Then I said to have a nice day and hung up.

Had a few calls from this number but did not answer. Who is the caller?

Constantly ringing at all hours of the day, I have never answered the calls as the number looked strange. Googling the number reveals that it is Virgin Media with some kind of marketing scam.

you will sometimes see this number on caller id when someone calls from the UK and they are using the 3 network International Saver option (caller has to dial 388 before the number). Sometimes the true number appears on caller id and sometimes some other strange combinations like this one.

California shows up when you try to return the number
