Hello, if you received your ingots, then you should have been charged for it, please send a screenshots to Customer Service via a ticket, showing your transaction number, as well as your red envelope event displaying that you had not received your rebate (if you still have it), they will be able to assist you better. Sorry for the inconvenience.

That is okay, just please send whatever you have to CS, and they will be able to best assist you, sadly there is nothing I can do from the forums.
