This is the best suggestion, but unfortunately may not be possible for them to recover everything depending on how they paid/their credit card company. Most banks only allow you to do a chargeback for charges within the last 1-2 months on debit purchases and 6 months on credit card purchases.

Do the 1-2 month chargeback, and then when you've got that, take the company to small claims court. The chargeback may bring you extra weight (or not, IANAL).
