this is from the scam company credit card services...not the obama campaign. Your unlisted number means jack [***] to the computer program that dials numbers at random. Get over your hatred and stop posting unless you actually answered the phone and can contribute meaningful information about the person or company who is violating the do not call list. BTW.....political calls are not covered by the DNC list and anyone can get your unlisted number.
Plug your phone line into the modem on your computer and install software for Call Forwarding. You can set it up to forward all calls that are out of your area code or whatever numbers you choose. Then forward the number to the FCC or FTC or gov agency of choice.
This is from Credit Card services. I have gotten the same call from over a dozen numbers across the US. When I block one, a new one shows up. It's never ending frustration but luckily I can easily block these using a phone blocker that I bought at Amazon.
