Just sold my most expensive car and did not receive my CR

I need help and some advice, I just sold my 2011 Lamborghini sesto elemento forza edition and the CR never came to me but the cars gone and yes I already collected it. It’s even in my alerts that the car was just sold. I’m not going to play until I find a way to get them back bc I don’t want these auctions alerts to disappear just like my CR did, Can anyone help me on how to fix this, Thank you.
