They call and leave this number for me to call them back at.. they say they have imparitive information they need to share with me and that if I don't call them back they will file legal suit against me...

who is this number

Please see comments under phone number 951-737-4800 which originates these calls.

This is a scam.

I got the same call.  I called it back last week and he asked to verify info (I didn't tell him anything he just verified what he already had) and then he put me on hold to pull "legal papers" and after several minutes I was disconnected.  I was really worried because I probably shouldn't have verified what he was asking.  I didn't hear anything for a while and now today I got another message.  I GOOGLE the phone # and all kinds of company names come up.  What the heck is this thing?

They are a joke!! They called me left a message about how they are going to sue me. They wanted me to verify personal information like ss# and I refused to!!!! SCAM!!!!!
