the number called me three times within three hours and left no voicemail.  When i finally got a hold of someone the speaker had a thick indian accent and began asking for my phone number before telling me any information.  after asking him a few times what the call was in reference to he said something about an IRS lawsuit and asked if i knew about it.  I said and didnt and he proceeded to ask for my name.  

I told him i wouldnt tell him any more information and if he was calling about a lawsuit he would have information on file, so i asked again what the call was in reference to and what information he had.

he then paused and mumbled something, told me not to worry about it and hung up.

out of sheer boredom i called back repeatedly within 5 minutes and no one picked up.

ill continue to call this number back to try and fish more information about them and their goals hopefully to help people not get scammed.  I would assume posing as an IRS related laqsuit after name they would have asked, address, followed by social security number.

Ill update if i can get more info i nthe future
