Cannot delete a Search Service Application

That's almost 2 days that I'm trying to delete a Search Service Application (called "GroupA") and when I click on 'Delete' the thing is running endlessly until timeout.
I created a Managed Metadata Service for it but that one I successfully deleted it.

Everything begun when I made a User Profile Service Application (called "GroupA profiles") specially for that one and I ran it. Everything was ok, I set the good connections to LDAP (3 domains).
After that, I wanted to make another User Profile Service Application (called "GroupB profiles") for my second Search Service Application (called "GroupB") but then the profiles sync won't start and from there came all the trouble.

Now I want to delete GroupeA but I got some errors. When I click on 'GroupA' search service app I got;
