Very rude.  I said "no thank you" 4 times.  The man attempted to argue and belittle me.  It's abusive.

Get a whistle and blow into the phone when they call and hang up.

These people who ever they may be are annoying. They call day in and day out 7p.m. on the dot. Will not stop calling me! Super annoying.. I am on the do not call registry for a reason.

This 800 number is a scam don't call it. You wind up with more calls!
