I left my iPhone to change a battery and I collected the phone with a broken screen. A guy said he will change the screen for free. I went to collect the phone again, he said that the battery needs 12h charging. I charged it. The phone doesn't work at all now. I complaint and then the guy shouted at me that it happens and it's not his fault. He also told me "Now be quiet and listen to me! Don't speak now! Listen, I have a shop 20 years and I know!" That's ridiculous! A graphic processor has been damaged during changing a battery. Repair would cost me more than 100 euros, which doesn't make sense in iPhone 5s... The shope doesn't agree to pay my money back.
