Feel sorry for your problems, hope it resolved soon. I will remove the pool from ANN and the pool directory if he don't resolve the problems on time. You can try visiting the main site: http://pool.ahka.net/ join any Discord group for each coin and find the pool owner there.

On the pool http://pool.ahka.net/arto/ scroll to the bottom, put your wallet address there and take a screenshot from the resulting ouput (pending coin etc.) as an evidence.

Good luck!
