I have talked to support, and yes they tend to be quite crappy. I only know two companies doing it right. They're usually the underdogs on the market, providing the same service as their bigger competitors only much better and with better support. Xs4all is an ISP in the Netherlands, not one of the biggest but definitely one of the best. Spotify advertised so much that they worked Grooveshark out of the market, but Grooveshark's support is sublime and they're also cheaper than Spotify.

Most companies have "almost acceptable" support. You can talk to someone, they talk back, and most of the time (not always) they can solve your problem within 40 minutes of waiting on the phone and forwarding you to 6 others.

Then there are companies like Google and Microsoft. They deliver products, not support. Having trouble with Windows? Try talking to whoever delivered your pc. Not those who made the product and know everything about it, instead you talk to the person who sold you the system. That's like asking a 17-year-old working in a supermarket about why the doctor prescribed a product of theirs. Smart move by the doctor though, he makes way more money when you come in than when he explains his prescription to you on the phone.
