Hero Evo cosmetic has changed to a hideous green

So I did the hero Evo on my ledley king and it gave a nice purple cosmetic design to the card it's now oddly changed to a hideous green design  , I'd like it reverted back to what I paid for the purple design which was the major selling point of this Evo, if not I want my coins back which I believe was 100k as I didn't pay for this hideous green card design, I await a prompt response
