If, as a previous poster reported, this is an agency doing fundraising for a charity, the Do Not Call list does not apply. They are supposed to place you on an internal Do Not Call list if you request them to. If they refuse or call you after a reasonable interval, say 5 business days, then they are in violation and can be reported.
Don't give them a penny, they keep most of the money for themselves. If you want to give to the Vet's contact your local VA and ask them how to support them. They are nothing but a scam.
Received a call from 650-644-4123 did not answer. My number is on the do not call list - that seems to
be a joke. Still keep getting unwanted calls. Will not answer the phone if I don't recognize the phone number.
Call on caller ID but line is a line I have connected to my printer which answers as a fax machine so when they keep getting a fax machine they may quit. Since I've set up this way I find few call back as their number is no longer showing up on my caller ID.
