The number is "Rick Castle's" #.  He has a foreign accent and says he works for IRS Audit Dept and that we owed some back taxes from '08 - '13.  HE knew some information about us but he had very bad phone connection and just answered my call back with "hello" nothing official.  His "Senior Officer is to call us back today with more info.  My husband and I both missed work today to wait for the call.  They are pretty good with convincing you.. at least at the beginning.

They called me with the same story , but I had a hard time understanding them. I told them I was going to the house to call the IRS. Thats when he threatened me with an arrest warrant, and prison time if I did not pay him Immediately.

Got the same issue today. Threatened with a lawsuit and was actually told that an agent had been to my house to deliver the information in person. I actually asked him why he had an American name Kevin Wilson Id # W2195 when he had such a heavy Indian accent. He ignored this. The IRS doesn't work this way according to their scam reporting page, which Is something I suggest that you do immediately if you get one of these calls.

Got a call from 1 202 697 9197 telling us that they were the IRS and was going to take legal action against us. It was too late when I found out about it, Got hit for 5 grand. Same story someone coming out to tell us what happened.They gave us this number to refer back to.Rick I hope you read this because I'm comeing after you , and when I find you ,your BALLS will be hanging on my wall as a trophy!! Rick you have messed with the wrong MF, You better sleep with one eye open you [***]!!

Problem is, nobody knows who they are, just one out of thousands in India and Pakistan who call from thousands of call centers.  Call blocker is your best bet.
