Warranty assessment inconsistency

I sent in my 2 month old iPhone XS for repair after a portion of the screen began to malfunction and locked me out of my phone. I had barely used the phone in the two months as I was waiting to purchase a cover, which I did about a week after having the phone.

After some back and forth trips between the store and the high value repair centre I am being told now that my phone has failed it’s warranty assessment due to a dent in the camera lens. Note, my camera functioned perfectly and have dozens of picture to prove this, the phone was never dropped or damaged. The initial booking form noted no defects on phone on inspection by the store consultant. As per the warranty I was informed that factory defects result in You getting a new phone replacing your defective one. Upon calling the repair centre they i formed me that I will be getting back a second hand refurbished phone as a replacement.

I think it both exceptionally unfair that I am to get someone’s refurbished hand me downs. I have no idea what faults this phone is coming with or who has used it before me and what for.

It is absolutely unreasonable that MTN expect people to keep their phones in box quality for the first six months. In that instance I may as well not use my phone and have no need for the warranty at all. Micro scratches are part of wear and tear. A simple act of placing my phone on a table could result in a scratch. It’s unreasonable that a phone can fail a warranty assessment because someone used a microscope and found a scratch somewhere on the phone. Even if the grounds for a dent in the camera, that is inconsistent with the defect. Moreso it’s unfair that I’m being forced to accept a second hand phone because of this.
