Apple

Here's a great  example of how NOT to do great customer service. 

Regarding the iPhone 4's reception problems, Steve Jobs says (1) It's a faulty design, but (2) Everybody else does it, too, and (3) Not too many customers complained, so (4) We'll give you a cheesy looking "bumper" as a quick and dirty patch, but (5) If you don't like it, we don't want to sell you one, anyway, so there. 

What an arrogant S.O.B.! Combine this with the signal strength bars thing (they've been lying to us since day one -- you're okay with that, aren't you?) and the rash of iTunes Stores hacks (Got a problem? Contact your credit card company, not us), can one imagine a consumer company with a WORSE attitude towards the customer? Hey, we're Apple, love it or leave it, chump. We don't have to provide any customer service -- you'll buy our stuff just because it looks cool.

Honestly, would any other company get away with this crap? I'm having big problems justifying upgrading my current iPhone. Why should anyone buy any product from this arrogant, self-centered bunch of assholes?

But that's just my opinion; reasonable minds may disagree.
