This article helps with: Why have I been charged more than once? Why do I have multiple charges? Why is my transaction showing as pending?
If you don't reach the confirmation landing page and have not received a receipt after your purchase, your entry is considered 'pending'. In situations like these, the bank can hold the funds for up to 2-5 working days after the attempted transaction. After this time the money will automatically be released back into your account.
If your money has not returned after the above duration, please submit a request to the Win Happy team.
