I have a problem with my apple id and app access

Recently, my Apple ID was blocked without being able to restore access to it, but my purchases remained on the same account. After talking to the support service, I was told that I should contact the seller and explain this situation to him. As for the receipt, I could not find the receipt in my mail, but my account must be registered with you… ( my account, through which I made the purchase - bektursun220999@gmail.com)

Developers have no access to Apple’s systems, so I’m surprised Apple support would tell you to do that. Your purchase is tied to an Apple account, and Apple are the only ones who have the ability to verify that you have purchased the app or apply changes to your account:
