I recently had an appointment to replace a cracked screen and the service rep said she needed my passcode to do the repair. I asked to talk to the manager who backed her up. When I said I didn't feel comfortable with that and where this "policy" was that they kept referencing, they canceled my appointment and asked me to leave the store. They never told me why they wanted my passcode other than "to check some information and run some tests." Has this happened to anyone else? What is going on?
