No idea what you are talking about with a modded server.
OP. You need to report this to support. If you can get online in-game long enough then go to the cog icon Settings -> Help and Support -> Contact Us/New conversation button in the top right.
If you can't do that then email them at
clashofclans.account@supercell.com
You need to be very patient, an initial response can take 24 hours generally but with the new update and the problems you could be waiting even longer. It could take many days or even a week of delayed back and forth before they finally ban the account to block the other person out and verify ownership with yourself.
Good luck.
