My husband and I recently donated to the foundations for our children's schools. One foundation didn't receive their donation for 6 weeks, the other still has not received their donation and it has been 7 weeks.
This is very unfortunate because the money actually left our account at the time of donation, so Just Give seems to sit on the money for extended periods of time before giving it to the intended recipient.
This delay is not mentioned on the website - one of the foundations we donated to missed out on a matching donation because it was not received in time (though we paid for it in time).
I have tried to call Just Give on the phone and no one ever answers during normal business ours. I have left multiple messages and have not had a response. I DO NOT RECOMMEND USING JUST GIVE!
