I bought overwatch account for 28 dollars and did not work. but I cant find cancel option do I have to wait 3 days?

I would like to refund my money but I cant find cancel button or any refund option do I have to wait for 3 days before I can see my cancel button or after the 3 day is done do i get my money back? because the item i wanted did not work.

Already got my money back thanks gameflip great website.
