I just a call from them too. They didn't answer when I said hello so I called them back. Some law enforcement organization looking for money. Told them to put me on their DNC list.
They called to, hung up, I called right back and a man said hello, I said you just called me? He just hung up! What a jag off! I am on the DNC but yet I get at least 2 calls a day from telemarketers etc. That DNC system is a worthless waste of taxpayers money! I hate them all!
