Donation.

Hello! So, i have a little problem, i wanted to donate 10 euros. The site kept popping up an error saying that the transaction failed so i tried again. Well, again, it didn't work. I verified my bank account and 20 euros were missing. Now, the other problem is that i didn't get the points as well. I would like to get some help on this problem.
Is there any chance to contact a Gm and how?

If it said that the transaction was not completed, the money should be automatically returned to you in a few days.

It was most likely caused by Paymentwalls fraud detection system. If you still want to donate, you have 2 options:
1. Contact Paymentwall support (they will most likely ask you for pictures of your card and some documents).
2. Use prepaid cards (like Paysafecard or Mint) or gift cards to donate if you have those payment methods available on donation window.
