At the same time, I think it is naive to expect a customer support rep in the Philippines to handle this sort of situation. They do not make 7K in a month. If they bought the empty box at a brick and motor store, I wouldn't expect a cashier to be trained in dealing with a 7K fraud issue, and the general manager may not be able to resolve it on the spot either.
My guess is they eventually did a google search, and thats how they found advice telling them to email jeff@amazon.com. They have a large team of people managing that email and advertise it for situations exactly like this. Its hard to interface with a 2 Trillion Dollar entity but I think it's fair to say they do a ok job.
