I live in Chatham, On which is where everyone is receiving these calls from. It's a call center called Millenium that try and collect donations, but collect more than 70% commission from the donation. So it's pretty much a scam. They use charities such as firefighters, cops, kids safety, etc.
If you do want to donate to these charities, do it through them directly. Never over the phone.

They call repeatedly.  I've now decided that I will never donate over the phone again.

Fire chief office

Phone rings, as soon as you pick up, "they" hang up.."They" called couple of times, so far I never talked to somebody...

Was a very attractive woman on the phone. asking me to donate monies to firefighters charity, I asked for the charity number ans she swore at me and hung up. Must be a scam, and she was probably fat and hairy, mole covered and stinky!
