The caller claims to be collecting money on behalf of MADD (Mothers Against Drunk Drivers) however that name is not in the Caller ID only 6042824564 is where the name should be. This indicates it is a VOIP spoofed number. A charity has no reason to be trying to hide their identity. They could be a Fundraiser raising funds on behalf of MADD however by law they are required to state this at the outset as fundraisers can keep up to 90% of any money you donate for themselves. Therefore my opinion is that these are scammers. If you want to donate to a charity do it to the charity itself not to an anonymous phone caller,
