Things people tried to scam me on, but I didn't fall for; IRS, Social Security, Electric Bill, Microsoft.
With Microsoft, I had just bought a new computer and just got it all put together. Not even 45 minutes later I got a phone call from a guy with a thick Indian accent saying that my computer had been compromised. I replied just before I hung up on him, "Dude I don't even own a computer,"
With the IRS, they kept calling me, I kept hanging up. I did though go to my local IRS and talked to them in person. After taking my information, they said that I was good and didn't own anything. After that, I did a trace on the number and called their local police department, in Arizona, and made a police report. I haven't heard another word from them since, and that was over 5 years ago.
I did though fall for one scam, but only once. I thought it was a job that would allow me to work from home, but ended up loosing a little bit of cash instead.
