Apparently my phone number was sold. I never sign up for anything, so I'm really hoping someone hasn't been using my phone number to sign up for things. All week I have been bombarded with calls from random numbers. Every time I search one, it shows up on the telemarketer/scammer/rewards list. I got a call from this number 8:54pm (cutting it awfully close to breaking the law), obviously, I did not answer, and naturally there was no message left.
Seriously, you think they're at all concerned about breaking the law by calling after 9? They've already broken the law by calling people on the DNC Registry.
Most of these are robocalls: start at -0000 and keep going to -9999.
Don't call back. When you pick up the phone, they hang up, hoping that you will call their number. Then they will have skirted the DNC law, since they didn't try to sell you anything when they called; only when you called them.
They made the mistake of calling a state cell phone assigned to a Lt. with the CA Highway Patrol (me). I called them back advising them that they were violating state and federal law and if they should call again I would refer the matter to the state AG's office. Needless to say they were more than apologetic "assuring" me that my state issued mobile phone would be removed from their call list.
Your best solution is to press the option to connect to a representative and get as much information as you can about them while giving them false information about yourself in the process. Then tell them that you will use their information in a complaint with your state's AG. Incidentally, in many states they are subject to a civil penalty payable to you. If they are calling from within your state the odds of collecting that penalty are quite high.
Diogenese, proof that they initiated the call is evidenced by your caller ID but that proof is not required to pursue an adverse action as allowed by law. To call them back to complain and/or glean identifying information to bring an action against them in no way mitigates their actions nor does it nullify any recourse you may have.
