Forza horizon banned

To forza,
Can you please unban me on Forza horizon?
I have been banned once before for no reason what so ever and i am now banned again due to the fact that someone who i don’t know on my friends list has sent me a unicorn car.
Not only have i been banned but he hasn’t.
Please can you unban me my Gamertag is KRAZYFACEKILLER
