Calls but no answer

Claimed they were apart of a law firm trying to get ahold of another employee where I work. Heavy accent.

Heavy Indian accent claiming to be Chris Matthews, six months ago exact same scripted message from Robert Richards and six months before that he was James somebody. Each time the number to return the call is different and each time I finally answer and speak to him to tell him I know it's a scam he claims it's the first time he's called me. I inform him I know the legal procedure for bringing lawsuits against someone and they obviously don't, that I've got his messages recorded on my work cell and home phone under all his names and that I've reported his activities to the attorney general's office, the Ca Dept of Consumer Affairs and posted messages on web sites like this, and he suddenly hangs up on me! Imagine that!

Someone named "Joe" called saying he was our business' Embarq represenative (even though we already have one) saying he is reorganizing our plan and needs to fax me something that I need to sign. Now I don't answer this number's calls. Sounds like he is in India, not very professional sounding.

Called but didnt leave message I didnt answer since I dont know the number and a prefix 000 sounds weird to me...
