Samsung really bad and poor after service

So I had a phone brake because of a defect the brand new Samsung s8, I explained the whole defect to samsung and they refused to help, they basically said it's not there problem, first they said my phone is not under warrenty because we failed to call in with in 31 days to register the warrenty, and said the shop should of told us that, they also said there is no more free screen replacement in the first year, so I got hold of cell c were i got the phone and ask why they never told us any of this and they said because they never knew, they said they only received a email on the 7th of August telling them about all the changes and the new format of warrenty, they even sent me a copy of the email samsung sent as proof on this, but I got my phone in may three months before all the changes took place, so that can not be fair or right. Samsung SA got back to me today and said the screen is cracked and there for they can't warrenty the phone untill we get the screen replaced on our own cost, R7700 the phone was never dropped or bumped the screen cracked because the screen lifted up putting the cover back on after wiping the phone down, so it was not because of damage but a defect, samsung even refused to take a look at the phone, called 10 shops today and 9 of the 10 said they are not aware of the changes, spoke to 20 people with Samsung s8 phones not one of them have called into register their phones and they all say they same they were ever made aware they had to register it, me I have never had to call in to register a phone for warrenty and almost every device I own is samsung, tv micro wave even my watch and tablet are samsung, and I never had to call in on any of them to register it, now I have to, the cell shop can't be blamed they never knew, it is samsung fault but they refuse to help me at all on this matter, I have attached a picture of the reply from Samsung SA as proof of the issue, so that people can see the truth aND rather go for a brand that will be with them till the end and look after them. I will never let this issue rest till it has been sorted out, devise replaced or repaired but I will not be paying r7700 on a screen that is a defect, please any comments welcome if you would like to get on contact with me just leave email address so please before you buy a samsung s8 think about what is covered and what is it covered, think about how they would not help with a defect on a phone enjoy caused by manufacturer defect, if the phone was dropped it would be a different story but even then I would not have been made aware of the new warrenty I only found out because of the defect, let's hope samsung Getz back to me with a solution and not a excuse this time because thus far that all I been getting but I believe that will change so I beg of you all that view this, please think it though really nicely before making a choice because it might land up being a really expensive and useless choice, rather go for a phone that gives what they offer atleast I still have my s7 which I replaced my screen at my own cost 3100 IT COST ME after I owned it for two years,
