Have received several calls, didn't get around to blocking, but will do so now. Caller ID is "Sherman Oaks." I never answer and they never leave a message. I suspect it is a spoofed number
I received the same call this afternoon claiming his was from Windows Operating system and his name was K Zing (heavy Indian accent) try to help me remove malicious software. He did have my name. I asked him to remove my number from his database and he hung.
Called me today, said his name was john smith and he was from Windows. I get one every month always from a different state but always with indian accent and always with american sounding names. That is when I blasted him with my air horn.
