I have a defective MacBook, how can Apple Care help?

It took me less than a minute of research to invalidate that claim. The AppleCare+ Terms and Conditions clearly and obviously state only accidental damage is covered.

by far the easiest and most frequent cause of lagging performance is added Third-party software such as virus scanners, optimizers, cleaners, speeder-uppers, or a VPN you installed yourself.

You may not have ANY hardware issues at all.

If you want an official answer, you need to ask Apple and they do not address such questions in these forums.

We are end users like you here for mutual tech support. We cannot support Apple policies other than linking to what Apple have posted. We cannot give you a binding answer.

I suspect the guy conveniently "forgot" to tell Apple the truth about deliberate damages to the device. Those are never covered. That evidence would not even stand up in a TV court of law run by a dyspeptic donkey. I recommend you NOT mention any online videos when you talk to Apple. The truth is severely lacking in online info

so should I expect apple store to give me another Mac like mine? (And how they can do so, since I have a custom one).

From experience, I can say that Apple now sends most devices to a central repair facility. Very little repair work is done in-store any more due to lack of space to inventory the myriad parts needed to service so many product lines. If the device is fixable, they will rerun it to its original configuration—even if custom—and, if not covered by warranty, will give an estimate for your approval.

What are the options in my case? what do they do in such cases?

Add those to your questions for Apple. As this involves Apple policy, this is far beyond the scope of user-to-user tech forums.

The computer needs to be inspected by an authorized service center before Apple can advise you what is wrong and how to proceed with repairs.
