Can Someone Help Me??

Right now, a level 14 is farming me(lvl 12) and I can't get him to stop. He has 20k cav and attacks me, my oasis's, forts, and subs each five times a day. I've asked him to stop and his only response has been "hahaha". And I have never done anything to him(never attacked him, talked to him or anything!). I tried asking my alliance members for help but they are either too far away or can't deal with his army. If anyone could help me(I'm on Server 5) I would really appreciate it! My attackers name is Night_Fall and I would be eternally grateful if you could get him to stop attacking me!

You can contact a high player, to ask for him to kill him
