On a bit of a tangent, something very similar happened to me recently -- splashed out ~£300 for a product and after about 4 weeks of no further contact from the company, turns out it was a scam, and the sender shut down the corporation, website, wiped it from the various archive sites etc.

Fortunately I'd paid using my Amex, and American Express support were incredibly helpful in making me whole pretty much right away. I recall the payment gateway being a Stripe thing, so I really hope the scammer got hit hard somehow.
