These people won't stop calling me.  I'm on the National Do Not Call Registry and on numerous occasions I've asked them to stop calling me.  I'm at a loss as to how to stop these calls.  Is there anything annoying I can do to them to get them to take me off their list?  

If I had their address I would go there and cut their phone service.  I would be willing to join an army of other volunteers to attack them and destroy their business.

Also if you dial the 407-565-9999 it will tell you it's not a working number???

Same for me "Junk Call" anouther for Ooma black list.

Florida 407-565-9999 rang twice and I picked it up but they had hung up already.. too bad! I was all set to get my whistle out and bust a ear drum!

CC services..  You'd think they would get a bit smarter after blowing a whistle in their ear! Oh well, it keeps the calls down to like maybe one or two in a month..

Number and caller-ID are spoofed, making any complaint / DNC completely worthless.  You can't file a complaint because there is no way to know where the call actually originated!
