A recorded message saying that If I didn't call back in regards to Tax evasion they would issue a warrant for my arrest.

Caller: Robot message not known who

Left recorded message demanding contact or an arrest warrant will be issued with no details in regard to what it was about.

I rang once and got disconnected

Caller: Robot voice - didn't give a company name

This number left a voicemail on my mobile. They claimed there was a law suit case against me and asked me to call them back on this number to get it sorted. I've had a friend receive similar messages. I'm calling bogus. I ahven't done anything wrong to merit a law suit.
