(CASE WRITING) Last week you ordered design software for your boss, Martin Soderburgh, at ArtAlive, the small art consulting business where you work. As he requested, you used his Visa card to order Adobe Design and Adobe Photoshop from an Internet vendor, PurelySoftware.com.

When you didnt receive the usual e-mail order confirmation, you called the companys toll-free number. The operator said the companys website was having problems, and he took a second order over the phone: $649 for Adobe Design, $564 for Adobe Photoshop, including tax and shipping. Four days later, ArtAlive received two shipments of the software, and your bosss credit card was charged $1,213 twice, for a total of $2,426.

Your task: Strictly speaking, you did authorize both orders. But you understood during the phone call that the first order was canceled, although you have no written proof. Send a persuasive letter to PurelySoftware (create a plausible address for both your company and PurelySoftwares) requesting (1) an immediate credit to your bosss Visa account and (2) a postage-paid return label for the duplicate order.
