Does anyone know...

Does anyone happen to know how the Gallup pollsters managed to get my cellphone number when it's on the Do Not Call list? This is the first time I've gotten a call on that number that wasn't family, friends or the occasional wrong number. (There's this lovely woman somewhere in southern Virginia whose friend or relative has a number that's just one digit off mine. Every so often, she misdials and gets me instead.) I tried to cut the guy off politely - he's just doing his job, after all, and wasn't rude or otherwise ill-behaved - but I haven't slept well the past few nights because of this cold I'm getting, so it was hard not to get crabby about it.
