This number called me and I called back with a fake name. They told stated the name I use on facebook this is how I found out it was a scam. Then my mom called back and they asked for someone else (my mom called from my daughter's cell phone). My mom was told that the irs made an error and tried to get information from her. This is a big time scam and I have it marked in my phone they will stop calling just do not answer or get on the line and let them know you work for the irs or something I bet they hang up.
