I dunno' about hard to believe. I've had my share of screwed up orders, orders changed without my permission, wrong pricing etc. Thing is, none of them should have happened to begin with. Ordering by placing items in a 'cart' then printing out that 'cart' then receiving a bill for something that is different than the 'cart' just shouldn't be happening. (Whether its a price change or out of stock, either way there should be a system in place to notify the buyer that what they are seeing, and what is going to happen are two different things.)
Although with a couple of e-mails it usually gets straightened out just fine.
As for no comments in an open thread, (from AG) that in and of itself is a firestorm that I'd not even BEGIN to take part in from my side or theirs. Just no winning in that situation. CS is better when its done one-on-one between both parties, and addresses each individual situation.
