I walked into the apple store on a whim, just traveling in Montreal and my phone stopped charging. The staff was very helpful and friendly. They figured out my problem and though they were swamped, they got me in and out and solved my issue. Even suggested I make an appointment to come return the charger I had bought because mine was under warranty. Came back the next day and after a short wait, talked to the staff and got my money back, and a new charger. Great customer service, worth the wait.
