Hi Operators!
If you have not received your in-game purchase then can you try closing and re-launching the game. If you still don't receive your in-game purchase then please allow up to 24 hours as there can be delays at times.
However, if you still haven't received your in-game purchase after 24 hours then please contact support on one of the following support channels for further assistance:
