No Samsung Mobile Care Communication!

I have been a user of the Samsung cell phones for many years. I've upgraded to a S8+ in Aug 2017 my phone then got ****** and I received a replacement S8+ in July 2018. My screen cracked five months later which is now December 2018. When I enquire as to how much it would cost to repair, I found out that it would cost me R4600.00 if I had not signed up with Samsung Mobile Care, within a 30 day period, then I am not be eligible for the benefit. On both occasions when unboxing the phone, I was not told about this Samsung Mobile Care nor the 30 day period. The lack of communication is very disappointing and frustrating.
