This is a SCAM  They claim they are from windows technical department - they are not.  The gentleman on the other end said his name was Sean.  He had an east indian accent.  DO NOT PROVIDE ANY INFORMATION to these people.

This number has called for the last several days. Fake Windows tech. I recognized the number, the fella with a heavy accent was very rude the last few times he called...so today I answered in Italian....he hung up. Lol!!

This is a SCAM  Nobody calls from windows technical department.  I gave it back to them.  They hung up on me.  Made my day.

I have 4 missed calls from this number in 2 days. Don't know them so I never pick up and they don't leave a message. Really annoying though.

Not sure who those stalkers are.  Report to FTC 1-888-382-1222
