Glory Garage Auto Repair

I went to get my AC fixed and the guy is like I'm a Christian man and just wanna help he charged me a 100$ for labor and a 100$ for parts. I said ok are you sure this is what's wrong with it he said yes. So I said ok thank you plz fix it. I dropped my car off waited awhile went back and got my car and it worked only for one hour the guy is like well it worked when you left and I said ya but just a a hour and 200$ bucks is a lot for me. He checked it all again and said well I can fix it but it's going to be another 250$ to fix it and that's just labor no parts. This guy is just a joke and a taker no man of God.
