You can file a complaint with the FTC but with the volume of calls and Caller ID spoofing it's probably more trouble than it's worth. Every now and then some operation gets taken down and fined but it's rare.

Consider yourself lucky to never gets calls of this type. Between the out and out scammers and pollsters/political calls/charities (the latter categories are protected from landline junk call bans), I routinely get 3 or 4 a day.
