In order to get these companies to stop, you have to file a complaint with the FCC
It seems that every time I report a telemarketer to the FCC, the calls from that number stop.
I know that most of these companies have multiple phone numbers that they call behind, so, I've been reporting every call lately and the volume of telemarketing calls has decreased.
No message, called back and received an automated message regarding special promotions. Allowed me to request to be added to do not call list by pressing 1.
