Local Fire Department warning about phone scams using their CallerID. Let's take a step back. Stop giving money over the phone. Don't ever provide credit or banking information over the phone. Tell them you will find their official site online and make a payment that way, if they get angry or pushy it is almost certainly a scam.
It is increasingly dangerous to pay for things and make donation over the phone, don’t do it. Legitimate companies do not force phone payments and understand if you feel safer with alternative forms of payment.
