Envato GraphicRiver.net Unfriendly and unfair to consumers who make an honest mistake; "Gotcha" is their policy. Melbourne, Other

This company does not believe in consumer fairness. They run with the "Gotcha!" policy when you as an innocent consumer make an honest mistake or are misled by the sites they advertise on. I was searching the Adobe Illustrator Exchange and found an image I liked. The page did not disclose that the image was raster-based (Illustrator is vector-based and thus re-sizable). Having no reason to doubt something listed on Adobe Illustrator Exchange, I clicked the BUY button next to the image on the Adobe page Envato advertised on. This routed me through a series of web pages and after finally paying for the product and downloading it, I somehow wound up with an unusable raster-based image instead of a vector-based Illustrator image. I asked for a refund from Envato / Digital River and they refused. They acknowledged that I had indeed made a honest mistake somewhere during the process (and/or that their page on Adobe was misleading/incomplete), but their "Ha-ha, gotcha" policy dictates that no consumers shall receive any refund after paying and downloading an unusable image. This company and its associates are profiting from the honest mistakes of consumers (or Envato's intermediaries like Adobe), who believe they are paying for something that is not what they end up with. That is an unfair and a patently dishonest business practice. I was ripped off!
