I received this call too. It was a automated robot person. I called them back and the person who answered was an Indian man with a heavy accent. He hung up on me. I called back and an Indian woman with a heavy accent answered. I told them I was a 16 year old girl and I didn't understand. She asked me for my information and implanted dumb. She then asked for someone who I didn't even know and I told her wrong number. She said she would take my number off her list.
Recording starts in the middle of a sentence. What I could catch was "... Revenue Services." Note, it doesn't say "Service", as Internal Revenue "Service". Most likely a scam. Not calling back.
At 106 PM, today the 20th of May 2016 I received a phone call from a woman claiming to be from the IRS some sort of detective agency that I am going to be sued. Funny thing is if I owed the IRS any money I would not have received my small refund check from the IRS..
Computer voice stating lawsuit of some sort. Did not mention IRS. Just that my attorney needs to contact them. Will not respond to this scam. Already received at least 6 calls this year related to "IRS lawsuits". Scum !
