Request to restore the game save to the 27th

Hi
Because I made a mistake during the game, I would like to request to restore the game save on the 27th and delete the save on the 28th. And the game save can only be restored to the 28th and cannot be restored to the 27th, I need human assistance. 
If the game save cannot be restored to the 27th, please return the gold coins for all 3 upgrades of Agera RS (Body 4), and the car official can take it away and lock it
Would you please help me solve this problem? I'm looking forward to your reply, thank you！
