Uncollected cars from the auction house are still there after I deleted my save data entirely

Hi, I would like to ask for help about the cars I forgot that is in the “My Bids” and “My Auctions”. I deleted my save data because of a certain mistake I made on selling prize cars, so I could start anew from the scratch and get those cars again. But in my surprise, those cars I forgot to claim on my previous save are still carried over into my new game. At first I was like “Fine, I guess I’ll just claim those”, but I cant. I just want those cars to be removed from my new synced save.

I tried emailing forzafb@microsoft.com, but the response I got is:

Which I already searched the forums about this issue, and I saw someone said to email the forza devs to fix this issue which I did
