How can I recover my Clash of Clans account on iOS?

I have a problem,

I contacted the support of the game clash of clans in which I am trying to recover my account, but they are not willing to help.

Google Play used to be connected to the same email that I now have in Game center, but when

I log in to the game I have a different account than the one I want. Are you able to help me?
