Apple Asked me to Pay for Macbook's Malfunctioning Parts

Apple refused to repair the 2 manufacturing defects on my MacBook Pro for free. There is no option for only paying for the part they purportedly said you are responsible for. The parts of a MacBook Pro is so bundled together when it comes to repairing, that it seldom makes economical sense to repair if there is an issue (vs buying a new MacBook). There are no proper channels to appeal/escalate Apple repair resolution. Only via a general feedback form, or a general hotline. You have to pay for their malfunctioning parts if they say you should.
