Any other Apple Store is better than Arrowhead by far.
We've always had issues with the place whether be buying, repairs or returns I've never been treated so poorly as a customer. Needed a refund for a brand new machine, with a receipt, it's not complicated. We told them we got it at the Scottsdale store the day before, the receipt showed both an old and new machine with different serial numbers but they clearly just couldn't figure out what to do or want to take the extra step to find the solution.
Immediately got on the phone with the Scottsdale store we got it from, they even confirmed the receipt over the phone drove all the way out there and seriously in less than 2min they handled everything no problem and we got the refund.
Save yourself the stress of dealing with this Arrowhead store, until they start training their employees to represent Apple better, and go to any other store in the valley, you'll be glad you did.
