Government?
You've probably entered your number on the internet somewhere. That's where they get it. BTW that is a spoofed fone # [someone using Skype or some internet telephone program].
Ebil Guberment had nothing to do with it.
Also, your 'taxes' do not pay for your phone lines. Telephones are provided by private companies, so complain to Verizon, or Sprint, or At&t or Cricket or whoever your provider is.
Called to tell me that my windows pc was infected with malware, and they could walk me through the process of fixing it. I asked how they got my number. They said you provide your number when you purchase a computer. To that I replied, "You are not a very good scammer, because I don't even own a Windows based PC." With no reply, he hung up on me.
Just got the call...from Microsoft and that every time I got on to the Internet they were getting error messages (doesn't the error message pop up to and I'm the one who has to report it Microsoft?). Anyway if I log on to my computer they could walk me through to find the files. I didn't feel comfortable told them to loose my #. Couldn't understand them and can't tell you if it was a man or woman.
