Warranty claim and Cost of Ownership

My 2014 Renault Megane GTline Warranty was declined by Renault Warranty and now I am sitting with a R23.051.21 Bill. Unfortunately there seems to be no help from the manufacture (not sure if the dealer can do anything). Apparently it is driver neglect so the warranty will not pay a cent. So it is useless and pointless to have a new vehicle after all. I have been owning Renaults before and never have my claim been rejected ***ned Clio, Fluence and now Megan GTline). Now I am suiting with a bill that I do not know how I will tackle. In the first instance, this car is new at 57.000 km to be giving such problems. Secondly, it is under warranty (that is useless now), thirdly I am not given a courtesy vehicle from Renault. Now I ask Renault SA, is this how your busisenness operate? cost of ownership is way too high and now my family is paying the Big Prize.Renault does what it used to do previously before where customer comes after profit. How am I going to generate such an exorbitant amount of money that was not budgeted for? This is preposterous. Anyway, it is clear that Myself, my wife and Sister will not purchase Renaults again as planned.(We wanted Kadjar, Clio and Megan in Jan 2018). This is a nightmare happening in day light.
