Ingame refunds?
They will not give you a refund, because they are not able to do it (which means they have no system to restore).
You are out of luck, but maybe these things can be prevented in the future, if more people report such kind of things and they will finally bring in a (optional) confirmation window, where you have to confirm that you want to buy THAT stuff.
Sorry for you! :-(
Really? Major bummer… Imo 5g and 180 blooms are quite alot. . . Well Thanks for the reply.
