11/25 at 7:02pm  I received a call from 469-458-9075, when I answered a man in broken English said, are you ready to have your computer fixed now? I said nope and hung up.
11/24 I called Verizon because my e-mail contacts had disappeared, they said I needed to call Microsoft. I looked for the number on the internet and called and I kept getting India, Guam, Philippines, so finally I allowed one of them remote access to my computer and he installed malware and wanted $500. to uninstall it.
He just called again from 1-877-882-6820
