Received 2 calls w/in 24 hours from 206-822-2239. Female voice with heavy accent warns I'm being investigated by the IRS. Promptly filed complaint with donotcall.gov. Maybe it's time to sick the NSA on these scammers!
Received a call from this number and let it go to voicemail. The voicemail stated it was the IRS and that they were filing a lawsuit against me. I called the number back and a woman with a strong Indian accent answered. I told her not to call me again and that they are a scam. She immediately hung up.
