Hi! I just opted to add $10 credit but since I wasnt sure if I ticked one of the options I clicked 'back' on the browser and then again chose to add $10 credit so I ended up adding $20 which I do not want. It was mere accident because I did't know it already charged me $10 in the first place. So is there a way I can get refund for the $10 or reverse the transaction? Thanks!
