I'm among the many who have had incredible service from Apple. Whether it's help from front line reps, phone support, Saturday morning calls with tech supervisors, or the Executive Relations team, they have always been helpful, informative, friendly, and professional — gone the extra mile — and resolved all issues!
Service under Apple Care has been exceptional, too, even including “no questions asked” replacements. They've sent out free-of-charge mailing boxes and returned repaired devices within a week. It's been impressive.
Given that, it's inexcusable what the OP, Maggie, has gone through.
However, I'm deeply perplexed how this went on for two years. The problems were there from the get-go. Apple Care takes care of things quickly. This should have been resolved in one to two weeks, not taken TWO years. Why the delay? I realize users can be busy professionals, but demanding a fix within weeks given you paid for Apple Care should have been high on the agenda!
There's also a major gap in the story from the first couple of months of working with Apple to suddenly it's two years later and you're disgusted.
What happened in between? Did you compile the logs they asked for? You could have helped Apple troubleshoot a basic problem with their new laptop. Did you ever demand a replacement?
Also, if you're not getting satisfaction, you should generally escalate the complaint to higher levels. “Being patient for two years” is being incredibly passive.
Plus, you had the option to cancel Apple Care and get a refund on the remaining balance — or, demand a complete refund as they didn’t live up to their end of the contract. That doesn't fix the laptop, but you'd get some money back.
I’m also perplexed by the issue you had. In years of using Macs, and reading forums, I’ve never had or read of a situation where a Mac could only run one app at a time! That’s just bizarre.
I realize this is has been a teerible experience for you, but a sweeping condemnation: “Beware: reliability and customer support is gone” is hyperbolic and doesn't withstand scrutiny or mirror other people's experiences. While I’m among those who would argue Apple's reliability and quality control have slipped, especially in the software realm, I’d never say that they are “gone”, and would never say that about their customer service.
Don't give up on Apple. Yours is a rare experience.
Even now, you should drop an e-mail to Tim Cook outlining all that’s gone on. Executive Relations will likely respond and make things right for you!
