We have had contact with Apple support about three times since 2007 and every time they were both reachable by phone and extremely helpful. Last time there was an issue with ordering Apple Care for a MacBook leading to the amount getting subtracted from our account twice. It took only a few minutes to escalate it from the first line of support to their financial department. After the issue was solved, they called back after a week to make sure things were also good on my end. Same thing happened when my wife had an issue about 10 years ago, not only were they very helpful, they also called her a week later to make sure everything was up to her expectations. (This was in NL and DE respectively.)

The only other large company that I have similar experiences with is our ISP (KPN in NL) who are also really easy to get hold off and very helpful (down to helping you hook up your own fiber equipment).
