Ok, so here's the problem. There is some brain-dead severely mentally ill zombie vampire impersonator running around and pretending to be you, took a payment from a person who needed to get their money out of a gambling site, and very specifically promised to return that payment if the gambling site didn't pay out:


Either that, or it was you who promised that. If it was you then you need to refund the 210 euro, regardless if you call it a payment, a donation, or a beach ball - you promised, return it.
