File Formal Report on http://esupport.fcc.gov/complaints.htm to make a complaint to Uncle Sam, when you fill in the complaint, reference #09-C00090484 and say it's a related complaint filed on the internet.
Like I have said before, Don't answer this call, and program it in to your phone as "Capital One" then you can set your ringtone for that contact as "no ring" hahahaha I figure if these pricks thought it was important they would leave a message.
The also use the following numbers:
866-463-3018
800-955-7070
800-955-6600
909-390-4781
718-359-1082
And they should consider having their Robo-caller leave a message. Or actually hire a living breathing person (ooooo, shocking!). Not like there aren't any people out there looking for work, after all...
