Needing to return a device means that things are already going wrong, so we try to make the return process as easy as possible. It is heartbreaking to hear that you were turned away when you tried to do the return and then you are getting charged for not returning it. When you went to the UPS Store did you have the prepaid return label with you, or did you have the email copy available for them to help you print it? If you did not receive the return label, then you would want to reach out to our customer service team to have them send one out to you.
