Promo codes/Gatherer Achievement

I used the promo codes (REBEL, OLDBEN, MAUL, DINDJARIN) in the webstore earlier today, and it triggered the "Gatherer" achievement, is there any way to get that reverted? I've been playing since November of 2016 and am very proud of my F2P progress. I absolutely should have checked beforehand, but since the achievement text says "Make an in-app purchase" I assumed webstore promo codes would be fine since they are neither "in-app" nor a "purchase" (it says redeem not purchase when you claim them). I already created a support ticket but the response I got was less than helpful. Hoping for better news here.
