Earlier quoted context omitted.
This has always bothered me. People always say that Twitter and Google can't offer real support because they would be able to handle the number of incoming requests. But that's exactly what companies like Amazon and Wal-Mart do every day. For crying out loud, even Comcast (COMCAST!) has better support than Google or Twitter for their paid products.
Amazon is pretty top tier. Just being able to email jeff@amazon.com about an issue is huge (and I've seen people recount what happens when they get the forwarded "?" email). Also they will correct any mix up almost immediately and will almost always credit you when you ask (or at least throw in another free month of prime).
When Google and Twitter say they can't handle incoming calls or respond with anything other than automated email, what they are really saying is 'fuck you, we have no competition'...which works great until there is competition.
