3608075520 - called my cell phone and left an automated voicemail saying it was an urgent matter and the IRS is filing a lawsuit against me and I need to call the number back ASAP. I didn't call because I know it is a scam. My husband received the same call and he went along with them for a while and they even let him speak to a "manager." Both people had a very distinct accent. When he said he couldn't believe they hire someone out of the country to call him - they said FU and hung up on him. Complete scam! This needs to stop.
