Dear We Fix, my wife had her iPhone with you in May this year for a screen repair. After the repair the screen functions stopped working and you can touch it as much as you like without response. I attached a video. We took the screen back and you replaced it again as you said your screen was faulty but the problem still persists. I then took the phone back and Tapiwa from your Woodlands branch in Pretoria told me it was unrepairable. I claimed it from the insurance and they asked Tapiwa for a detailed report and he told my insurance that the repair was due to wear and tear after they today rejected the claim. Please explain to me how a new screen can have wear and tear damage and how can he tell my insurance this? His incompetence in your store is unbelievable and going to cost you a lot of clients
