Apple App Store Purchase Missing From Bus Simulator Account

I made a $1 payment through the Apple App Store between March 23 and March 27 for my account in the Bus Simulator game, where my in-game account name is Turkish Airlines. At the time of purchase, I was told that the item I purchased would be added to my account within a maximum of 30 days.

However, approximately two months have passed, and the item still has not been added to my account. No content has been delivered, and there have been no changes to my in-game account information, balance, or purchased items during this time.

I request that the service I paid for be added to my account immediately or that my $1 payment be fully refunded. I kindly ask that this issue be resolved as soon as possible.
