Exactly, but the thing is, Amazon looks like they went in completely ready to compete with the big boys like Wal-Mart on this level. All of the major retailers have call centers and phone numbers posted in their stores for people to call in. Major manufactures like John Deere and Ball and even Phillip Morris have consumer call staff.

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.
