PLEASE HELP forza hub rewards not working

The last few times I’ve tried to claim my reward money for Forza 7 off the Forza hub it’s said everything’s worked but as I go into the game and there’s no credits. Restarted the game, restarted the Xbox, even waited for hours and hours and still no credits so I’ve missed out on a lot of ingame money which sucks and it’s making me really not enjoy forza just now. How can this be resolved ?
