Some guy asking for Sarah, I said I'm sorry you have the wrong number, he said I'm sorry about that, but maybe you can help me, and then started telling me about some officer fund and I hung up, the whole call was weird. Is this legit?
It likely is, however, you're basically giving the solicitor your money instead of any charity. They hoard the funds and most charities by phone are the same way. The asking for the wrong person then throwing the "perhaps you can help me" is a common saying, then they're a chore to get rid of without hanging up.
