SAMSUNG WARRANTY

I sent my phone in for repair has the screen had broke after it fell face first. I know as a Samsung customer I am allowed a free screen repair within the first 12 months of purchase however when I sent it in I couldn't repair the phone as I didn't have proof of purchase reason being that I got a replacement phone from Samsung in December 2016 after their now defunct Sandton repair center lost my initial phone . I contacted Samsung for some kind of letter of proof that they replaced y phone so that I can get my phone repaired under warranty however I was told the following "Please be advised that when a phone is exchanged it does not come with a new warranty. The warranty continues from the date of purchase of your original device. If you purchased your phone over 12 months ago it means that the warranty for the screen has expired." I asked for official documentation that states the above as I was not aware of these T's & C's nor was I informed about them as it was the repair center that had LOST my phone when I had sent it in for repairs, it was never an exchange! Being told that my replacement phone doesn't come with a new warranty makes absolutely no sense when I was told that if I could log into my phone I could still signup and have my phone fixed under warranty. All I have asked for is official documentation that states that a brand new replacement phone's warranty isn't valid as it falls under the old phones warranty.

Moreover, when I got my phone back, the glass at the back was completely shattered when it had a crack in one of the corners.

I have asked for feedback from the people at Samsung but to no avail, my emails seemingly fall on deaf ears.
