Hello,
I know this topic been discussed many times, besides I might not get any reply from the admins back.
However, I have made 2 donations, I have the receipts of both donations but just got one reward code, weird? yes, I find it weird too.
what gone wrong? nothing - no browser closed, no redirect page, not disconnected, etc...
I can forward both receipts, name, email address to admins upon your request to check it up.
Thanks.
