Purchased wrong stash tab,what to do now ?

Hi guys,I have just made a mistake purchasing the wrong stash tab I didnt meant to,am I shit out of luck or could support change it to the purchase I wanted originally ?

Was meant to buy the "Stash tab bundle X6" for 110 Gold,and instead I've added the “Premium Quad stash tab" for 120 Gold and brought that by accident,I thought it was a quad stash= X4 the capacity & X4 of the stash tab itself,without pictures of what it looks like,it didnt really help.

I have emailed support,and just wondering if there're anything else I should do.
