Lost access to my email and can't contact support

Hi,
Someone stole my email address and unfortunately I no longer have access to it. I'm trying to contact EA support to resolve this, but whenever I select the "Chat with us" option and fill out the form, it loads for a moment and then redirects me back to the homepage.

I’m really stuck and don’t know what to do.
Is there anyone who can help me or tell me how to get in touch with EA support in a different way?

Thanks in advance.
