Cars and progress has disappeared

All my cars have disappeared and all my races I have completed have disappeared but I’m the exact same level I was before

All my cars and my races, that I have completed, have disappeared. My cash has even gone and the game has given me a BMW Z4 as my only car. I deleted a title update so I could get 999,999,999 just before I stopped playing the game. I don’t know if it has something to do with this. I’ve spent over £7 on tokens which I bought a car with and that car has now gone. What can I do about this problem? I should at least get the car I spent money on returned to me along with all the race progress Ive lost?

Are you a member of the Xbox Live Preview Program?

No, will that help?

It just might so give it a try is what I’d do for sure in this situation.
