Never Regretted owning a Samung until now - S8

So it's been 3 months since I received my Samsung S8, I got it through MTN on pre-order. The phone was delivered during the month of May. All good EXCEPT, I was not told by Samsung or my Service provider that I need to register my phone with Samsung Mobile Care. I went to the Samsung Service Centre in Kramerville and was told that I would have to fork out +-R4000 to have my screen fixed. How the HELL does that work. I phoned Samsung and was told by the Mobile Care Support, Gisele, that since my phone is already damaged I cannot qualify for the SMC. Of course if I knew that I had to register and pay a monthly subscription, I would have done so. My phone is basically brand new and I would like to have it repaired by a reputable company (Samsung) but I can't because its not registered. I am super disappointed by my Brand of Choice. Highly Irate that I can't get decent service. AND Mad as hell that they refuse to register me when my phone is only 3 months old!
