Coin donation

I donated 10 coins on this acc few hours ago,i wait 1 hour for coins to get on my acc but that never happend,i recive bank comfirmation for sale but still no coins,maybe i make mistake so i donated again 10 coins but once again no coin on my acc,so 20 donated but i still didnt get them....can someone hlep me and tell me what to do???

I've got the same problem at the moment, just donated to get 57 coins... Looking at other posts, it is because they have their DDoS Protection enabled and so it may be catching on that firewall. Hopefully they will notice these and fix our problem :)
