In the UK if the goods were over £100 and you paid via credit card, you could raise a Section 75 claim with the card issuer under the Consumer Credit Act.
I used to work for a large train operating company and the sheer number of people contacting us for historic departure info to support a Section 75 claim because the news came out that someone got a 50% refund on their season ticket was astronomical.
Alternatively… Small Claims Court. Amazon will drag you through the coals if you go the chargeback route.
