Tech Companies (Google, Microsoft)

"Got a call from guy speaking with foreign accent. Said my Hotmail account was compromised and he wanted me to verify info with him. I told him he was a scam artist and he was argumentative about he was not and would lock my email account. Told him go ahead, Hotmail was a free account and I would just create a new account and I hung up."

Court / Process Servers

"Caller left an aggresive voicemail addressing me by my full legal name and stating that there is going to be a case filed against me in court that will allow them to track down my location. I contacted the Multnomah County Court house with the fake case number left on my voicemail and the courts stated that the claim number does not exist!"

"Said his name was Joe with an insurance company calling on a recorded line and wanted to review my plan. Then he asked if I could hear him ok and I know there are people trying to get you to just say yes so they have a recording of you saying that so I said 'no, not really' and for some odd reason 'Joe' hung up on me! Oh Joe, sorry but I'm not stupid!!"

SSA / Government Agencies

"The recording said they had an issue with my SSN - some sort of case against me. I called the number back and spoke with 'Officer Dale Johnson' who refused to tell me why he had called me.
