Company claims they are IRS - IRS never calls a client - they always send letters. They left a very aggressive message on my cell phone using my first and last name (which I reported this number to my local police station) and tell me that there is an investigation going on with my SS# as well as my address, and if I do not call them back they will contact the local authorities for a warrant for my arrest - make sure you do not say any information if you may call these people back - the person I spoke with was a "Maxwell Smith" who had an usually thick accent - do not say your name - just let them know you will report them to the IRS (which I did as well).
