I've read on other sites that this number is from some coupon sign up on Facebook. My wife must have signed up for it since we're now getting calls from this number.
Lucky for me the phone only rings once then they hear a disconnect notice, thanks to my old computer!
This number is a Debt Consolidation firm. When you signed up for all those free coupons etc this is a box you checked yes in. Just call it back and it will asked what number you want removed.
