I have a bumber that somebody else got for me as a gift. They do not have an iPhone or apple account.
I wonder how I will get them refund. I do have their receipt. It was not emailed to them.
Why even worry about getting a refund for this bumper? U bought the phone so according to apple you never got a bumper yourself. You can get another free bumper.
If you want to give the money back to the people who gifted you the bumper, then ask for a refund.
