Banned i think?

On Forza Horizon, i was playing with my friends and was sent a car by someone random. I didn’t think anything of it so i accepted it, but then later realized i didn’t want it. When i tried to send it back, it said error and then the car turned green. Then later, I had no access to the online paintshop or club garage, but i could use everything else. This was in June and i still to this day have a temporary disable, but I never received a message saying i was banned. Now i can’t get my rewards on Forza Horizon 2 because of this incident. Can someone please help me if they know what to do or how i can possibly fix this. Thanks

You need to write the developers at forzafb@microsoft.com with full details, including all gamertags which have been on your Xbox 360.

Don’t try the “someone random” excuse, though, because only Friends can Gift items.
