SEO Google Problem with new version MULTINLINGUAL (subdomain)

O M G !
I am really mad at the WIX support!

I just had their answer
I am struggling to make a great speach and get things done to fix the bugs of the new multilanguage version with the subdomains and give me completely stupid explanations !

So the support to decide to remove the subdomains to me again in the initial version.
What is the problem ?
