Faulty Apple watch series 3

I bought my apple watch series 3 in August 2019, terms and conditions state that my unit is under warranty for 12 months from date of purchase.

My watch is now 7 months old, and 2 weeks ago after I finished exercising my screen just popped off, I did some research on the matter and realized that this is a on going issue with some of the gen 2 & 3 watches.

I sent my unit in to a apple store after which they told they would have to send it away to get assessed 2 days later I received an email saying that my warranty was voided and I needed to pay R3000 to repair the screen with no proof or reason as to why my warranty was voided. My watch was in perfect condition.

I sent numerous emails asking for proof of why my warranty was just voided. I have not heard anything since!

Apple products are advertised as the best on the market yet when their devices are faulty they do not tale responsibility to fix it. I have been without my watch that I paid a lot of money for, for almost 3 weeks now with no feedback of any assistance from apple South Africa. Very disappointed
