CarX Drift Racing 2 Purchase Missing After Google Play Payment

Yesterday I bought a car inside the game CarX Drift Racing 2 through Google Play for 75, but the car never appeared in my game account. The payment was successfully taken, yet the purchased car is still missing from my garage in the game. After noticing the problem, I tried to solve it myself, but the car still does not appear in my account. I kindly request that the missing car I paid for be added to my game account as soon as possible, or that you provide a suitable solution.
