Not sure what you FICO (not FICA-Federal Insurance Contributions Act (FICA) tax)  score has to do with anything, especially since they ID'd themselves to you as the fake IRS and previous posts suggest the Microsoft PC scam, unless you're just bragging. Do not answer unknown calls and do not call them back. Consider getting a call blocking device (or app for your cell phone)-they're available online and start around $45. http://800notes.com/nb/search?q=call+blockers

I got a call from this number and I was online with HP at the time about my computer . I answered it and it was a voice bot. I thought it was HP so I answered it. Coincidence? ... smh
