If you used a good credit card. There is nothing a business owners wants to hear less than the word chargeback. Yelp review is like the broke / black / uneducated version of the word chargeback.

But, if someone is going to cuss me out or threaten negative reviews esp when I know I'm in the right, they can go all the way to hell and I will get the review removed. You're the sort of shitty customer I don't need.

He told you the screen fix may not work. You want him to repeat it for free? You broke your $600 phone. The problem now is you're taking it to a guy using a fake knockoff screen to repair it. So it's not going to get fixed there. Get it fixed the right way with Apple or buy a new one and stop being careless with expensive stuff and or get a case.
