Seriously? You actually expect to get something from the government for your tax dollars? In their world, you're lucky they let you keep any of your income.
When my answering machine answered, they hung up without leaving a message.
Their caller ID was the same as their phone number: 253-236-2698
I think it's the same scammers who used to repeatedly call me from 253-382-9923
I called this number back from my Skype phone so they couldn't trace it back (hopefully) because I wanted to see who answered, and I got a robo-voice immediately offering to remove my phone number within 72 hours if I"d just leave them my number, but I won't leave them my real number as I believe they'll just sell it to other call-scam-telemarketers as a live number that actually has someone there.
