prompt customer service
after receiving our phone we noticed that the battery would go from 100% charged to 70% just sitting there and not being used, and then drain quickly. Gazelle was phoned and 2 options given; to return the i phone or go to an apple store and have a diagnosis and if it is the battery, have it replaced and they would reimburse the cost. we did the second, submitted our receipt and the credit was given. really impressed with the entire process!
