The best course of action to take with the scammer calls is to find out what telephone service they use and report Fraud/Abuse to them directly. It can be found online usually.
The Do Not Call Registry is a fraud and a waste of taxpayer's money. If they actually DID anything to stop these calls to the public there would be a decrease in them, NOT AN INCREASE!!
Trying to sell a lower interest for credit cards, blah blah blah. I pressed 1 to talk to a "friendly customer service agent" and got Jason who hung up on me when I asked not to be called again. SCAM!!!!
I get daily calls threatening me about credit cards they've tried to reach me my phone and mail. When you push 1 after the recording you get rude men who call you an idiot and say your are crazy because you ask what credit card company they're with then they hang up. When I redialed the last call it says it something to do with the cancer society and the 2nd time it says its another charity organization. This company or people need to be arrested and put in jail.
