Ever heard of paragraphs? Your post is very hard to read as is, and that’s going to limit your responses.
That’s your problem.
Any mechanic who would deliver a car that “vibrated all over the place” is not to be trusted.
Didn’t they test drive the car after the engine mount replacement?
If not, why not?
If they knew all of the engine mounts needed to be replaced, why didn’t they tell you that in the first place?
I think you need a new mechanic, someone familiar with Honda engines.
And, again, paragraphs would really help. It makes my eyes hurt to read your post.
