They called all day yesterday and today even though I asked them to stop. They often use different numbers or "unknown".

Man identified himself said he was with Windows and said my computer was in trouble or something like that.

We have never had any dealings with them or their associates and we have zero debts.

I have been simply not answering the calls, but today I listened and then hung up.

Caller didn't have nerve to leave message

Caller didn't leave message. It's probably 1 of the 2, scammer for a charity. Been getting too many calls for money for police or firemen. Or 2, health care is back at it again calling people (real or not real ones).
