Shop Problem

I tried to buy the currency stash tab once but it kept telling me transaction failed or order failed. Then i tried again and nothing happend.
I closed the game and tried to purchase but i already had 2 currency stash in my stash but i wanted only 1.
Can i have a refund and get deleted the extra currency stash please?
Bu the way after that accident the website went in maintenance today.

Hi thanks for the fast reply,i just sent an email where you told me to.
I hope you guys can help me
