Google Font wont dequeue

I'm having an issue getting one of the google fonts to dequeue on my site https://subscriptionboxes.co.nz

I've done all the reading, and I can see it needs to be dequeued after its been called, but before its been printed, but I cant figure out how to find that info?

I also cant work out which plugin is making the call?

This is the code I have put in my child functions.php

function remove_google_fonts_stylesheet() { 
    wp_dequeue_style( 'googleFontsOpenSans' );
    wp_dequeue_style( 'google-fonts-1' );
}
add_action( 'wp_enqueue_scripts', 'remove_google_fonts_stylesheet', 12 );

It worked great for the opensans font, but the google-fonts-1 which is actually roboto, won't seem to go away no matter what changes I make.
