Need help with donating

So, I wanna donate 20e to buy some gold, but I can't. I only got Paymentwall as an option here in Serbia and they're currently not processing transactions from my country. I asked their support for an alternative but they just redirected me to Warmane support, then I asked Warmane and they redirected me to Paymentwall...

Tried sending to my friend in Las Vegas to donate for me, but when he tries he just gets a sad smiley face and it doesn't work...

So has anyone experienced the same issue and does anyone know how could I do it?

Thanks!
