A customer brought in their friends iPhone that they would like restored. Sounds simple enough right? I even asked if there was a lock, passcode, or Apple ID on the device and was assured there was not. Easy peasy!
Well as you may suspect, there was an Apple ID lock on the device, and seeing the prompt to log in after rebooting the phone was a horrible feeling. I contacted the customer to let them know that I wouldn't be able to get the phone to a functional state without the Apple ID lock being removed.
"So remove it."
I kid you not this woman just told me to remove the Apple ID lock. I had briefly explained why it was important to ask when she had dropped off the phone so I really didn't think it would be an issue. Oh boy was it.
I was told that "I brought this phone in here because you said you could remove the lock on it and wipe it clean for me"
I offered to give the device back to the customer free of charge despite the time spent on it as per policy, and even then was met with a poor attitude and disgruntled snark when the device was collected.
Don't(not that you can anyway) mess with Apple ID Locks and don't ever tell someone "Yep I can reset your phone for you" unless you're sure there isn't any Apple ID lock on it.
