Answered call today... Fundraising for my high school as well.
I questioned the fact that my school is in Brooklyn, NY and that the call is coming from New Jersey and they did say they were Lester, Inc. calling for my HS.
I asked them to send me an invoice or donor card because I didn't feel comfortable giving an unknown organization my cc #. If they were scammers, all they needed to find out was my name, phone number and high school. How hard can that be?
