Apple is ripping me off

I bought an iPhone X in November 2017 and the sales representative insisted that I should by an iCare Plus as it will extend my warranty to 24 months and it also comes with a screen replacement benefits, 13 months later the phone shuts down for no reason I took it to eastgate #iStore for repairs and I’m was quoted R12k for repairs when I ask why do I have to pay that much for an iPhone that has an extended warranty I was told that the iCare Plus that I bought doesn’t have extended warranty but it is written that it extends the warranty to 24 months on it, it’s even on their website https://www.myistore.co.za/help-center/icare. What’s kind of mind games are you guys playing with your loyal customers? I’ve been your loyal customer for 10 years for God sake! Bought an iPhone 4, 4s, 5, 6plus, X, iPad mini, iPad 4th gen and you are thanking me with a middle finger?
