You can't stop these people by reporting them. The FCC does not have the manpower to track down all of the scammers who spoof the phone number they are calling you from. The FCC would have to go to each of the companies that offer spoofing services and get records from them for a specific date, time, spoofed number used, and actual number called from.......ain't gonna happen people!
If you want to fight back you need to write your senators and members of congress demanding that spoofing services become illegal to use because there is NO GOOD REASON for anyone to spoof the number they are calling from if they have a valid reason for calling you. That way, the only culprit the FCC will have to track will be the company offering spoofing services.....much easier than getting all the scammers out there and that will also help the FCC enforce the Do Not Call registry which they can't do now because of this damned spoofing crap.
They are not credit card services...they are SCAMMERS trying to get your credit card information for their own use. DO NOT GIVE THESE PEOPLE ANY INFORMATION except instructions on how to "go to hell."
