I called the number back and it is an automated "generic" number used by telemarketers...it never said what company was trying to do the survey or whatever, but it gave you the option of being put on a do not call list.
I received 2 calls so far from this number,I called back, and a recorded massage directed me to enter my number to be put on a do not call list, they called again from a difrent number starting with srea code 202, and said something about car warrenty DO NOT GIVE YOUR INFORMATION TO STRANGERS!!!!
this number continues to call my cell phone and never leaves a message. i called it back and reached some automated system that requested my personal info. I have only been able to speak to someone once and it was a very rude young girl who wanted to renew a auto warrenty for a car which i do not own. she hung up on me when i inquired as to what her buisness was. I think this has to be some sort of telemarketing scam. BE CAREFUL!
