Wait. The device was within warranty and they gave you a "refurbished" (i.e. not new) iPhone as replacement?

I'm so glad this is blatantly illegal in various countries. They sold you a faulty brand new product, so they must give you a brand new replacement if they can't fix the defect on the device they sold you.

This is akin to telling the waiter there's a hair in your soup and getting a new soup that was returned by another customer but has since been re-heated and de-haired.
