I have not had to return anything there but I would think you would need proof of purchase. My friend has returned a couple things and the staff there was very kind and helpful without any problems. Also, if they still have your item in stock they may let you exchange it. Good luck with you issue.
Not sure if you don't have the receipt. If you still have the box it came in they might let you swap for the same amount.
I didn't return I just gave it to a family member and thank you.
