Well, you tried. Feedback is feedback.
Replying to the Translator/group how, little translating notes/comments affect your reading experience is a sound complaint.
Urging for a change in the format/style isn't bad either.
But ultimately, it is up to the editor(if there is one, if not then the Translator) to decide.

Seems like you didn't like their response back to you. My thoughts, dont take it too personal.
On another note, grammar wise I think your title should be critique instead of critic.
