If the seller doesn't respond to the reverse charge/ charge back claim, you will get your money back I would imagine. Its unlikely they will respond if its a scam. Even if they did you are good. Most payment processors will work like that were a dispute can be opened within 90 days of purchase. The bank will open this on your behalf. I'd be really suprised if you didn't get money back mate.
I did this last year with edreams, they were not responding to customer service requests, so did a reverse charge through bank, it took about 6 weeks but got a full refund 2000e and that was a legit company.
Also, noticed someone using card to purchase films on amazon, took a year before noticed it, got onto bank and they refunded pretty swiftly.
I work in I. T by the way, do the charge back thing and you should be good
