Clash of Clans Verification Code Not Received, Cannot Access Gmail-Linked Account

In the Clash of Clans game, I am unable to access my account when trying to log in from my Android device. My account is linked to a Gmail address, but during the login process, I do not receive the verification code to my email. I tried multiple times, but the code never arrived, and therefore I cannot access my account. So far, I have not contacted customer support, nor have I tried an alternative login method. My account is registered in Bursa, Turkey. I request that access to my account be restored and that the code delivery issue be fixed so I can log back in.
