Essentially, at the corporate level, Circuit City appears to have a policy against treating customers with dignity and respect. Their automated email on the topic of Wii game systems basically states, albeit politely, that we don't have any Wiis so quit bugging us. Their automated phone system (try this: 1-800-843-2489, option 1) somewhat courteously says: we can't help you, goodbye (CLICK).
At the store level, however, beleaguered but decent managers are doing their best to take care of understandably frustrated shoppers, despite corporate policy. The corporate folks could learn something about customer service from these individuals.
