I am getting calls from this and other numbers on a daily basis offering to lower my Credit Card interest rate. When I talk to an agent and ask which company they are calling from they will either hang up or lie ("we are calling from Visa/Mastercard").
I engaged one of their agent and got a call back from this company the next day:
National Debt Institute

866-331-2145
Ask for Nicolas DeQuattro and demand to be taken off their calling list. If enough people call, maybe this will stop.
They call and don't leave a message. I don't bother calling back because the call originated in Bridgeville, DE I just block the number. I don't know if there is a person on the other end or a machine calling as I did not answer it, but I was told that when you get AUTOmated calls, you can confuse the calling machine by pressing # repeatedly as fast as you can for about 30 seconds and it will confuse the machine calling you and spit your number out. Just don't say hello and start punching in the # sign.
They called me twice today but I was not near my phone to answer. Luckily my droid has a blocked number function.I added this number to the blocked numbers and now it will no longer ring, just straight to voice mail. I won't be hearing from them again.
