Redeemed code but didn't worked

Hello everyone =) Just redeemed the 25 golden keys code today. The code worked fine, got them out of the shift box, logged out and when I went to login again they were gone. Tried to use the code and it said i had already used it.
Is there a way to get the keys back?

Submit a ticket. Though I’m not sure if there even is a fix, I’ve had a ticket in about the same issue since Easter and haven’t gotten my keys.
