Donation went through but wasn't credited for it..
Made a donation yesterday and unfortunately at the end of the payment it came up with an error "Transaction wasn't Complete" but money was taken from my account.. I've paid for the 'premium membership' but it hasn't been credited to my account.. see images below
If it says that transaction was not completed, money should be automatically returned to you in about 1 week. If you still want to donate, you can either use prepaid cards like Mint or contact Paymentwall support to try solving the problem.
Just an FYI for anyone else having this issue, I had to disable popup blocker in firefox for the payment to go through apparently it was stopping something called 3D secure from working correctly.
