Just Giving sneakily add at the last minute, a 'donation' for themselves, to 'support' their own admin. They called it a donation to Just Giving. There was no question asking me if I'd like to donate to them. They took the 16% without permission, on top of what I donated, before I realised to late and had payed/clicked by Apple Pay. Disgraceful, sneaky, and I have asked for a refund.
