Forgot Security Questions, Insufficient Information Error, Live in Switzerland, Only Speaks English

I had made my AppleID account by use of my Gmail account, as such my AppleID is ******(gmail.com).

I am unaware of the last time I have signed in, but I do know my email and password.

I cannot use apple support because I live in Switzerland and only speak English.

Is there any way to rectify this situation, or will I never be able to manage my account?
