Samsung S8+ no communicaation about ADH

I have been a user of the Samsung cell phones for over a decade and upgraded to the S8+ last year. My screen cracked two months later, I enquired about repairs and was told that I had to pay R4000 cash to have it fixed, which I obviously shocked about as I was never informed that I had to take out cover, unlike the previous phones that were covered for a screen repair. If I was made aware that I was not automatically covered for a screen repair I would have made sure to take out cover. Now I am sitting with phone and a cracked screen that I cannot use because I cannot pay R4000 cash to have it fixed. I am disappointed that I was never advised of the cover ADH, I had to google it, to find out about it, Samsung have become very unreliable and the lack of communication is very disappointing and frustrating.
