I had a voicemail left on my office phone that said they were filing a lawsuit against me and to call them at this exact number. I called the number given and this gentlemen answered that this is the IRS and how may I help you. I told him I wanted all his information and questioned if this was truly the IRS. He said it was, gave me his name as Peter Samuels and Federal Agent ID# 10078651. He then said that I called them and what did I want. I told him that, in fact, they left me a message to call this number and that they were filing a lawsuit against me. I also told him that he called a law firm and I needed all information on this so-called lawsuit, which the call was promptly ended by 'Peter' hanging up the phone.
