Persistent guy calling reportedly from Nashua NH PD, looking for contributions for their fund raiser.  
They were using 603-591-2506, then swapped to this 774 # when the phone wasn't answered.  They also wanted you to call back 603-882-6400 (Mike Quinn Productions / Fundraising) .

I don't have a problem with the local PD fund raising, but when there's persistent calls with no messages, only empty hangups and then they change #'s to disguise themselves, it really looks
like a scam and I would never donate to anyone that annoys & continues calling and hanging up.  

They're calling businesses to boot, wasting valuable time/energy especially in today's economy!
