in that case, take your money first, go get a est to remove their bad tint job, and re do it. then say pay up sucker.
personally, i dont take this crap lightly, he would be fixing it for me due to seeing my f ing mug every day all pissed off at him.
and you can park your car and slander the crap out of him, as long as your claim is true, not a thing he can do. that alone should make him redo it.
make a huge ass sign for the side of your car telling the world how bad your tint job was, you can even paper the phone poles if you wanted to. just to piss him off, and loose customers to boot. park right out front his shop, let him call the cops, it will be a good laugh when they show up.
like i said, as long as your story is true, not a thing he or the cops can do, after all the customer is "always right" and your far from satisfied.
