Unable to Complete Two-Step Verification and Access My Account

For about one week, I have been unable to complete the second verification step and sign in to my account. I am trying to continue by using my Google account to sign in, and I have tried both call and SMS verification, but the codes and calls are not allowing me to enter my account. Each time I try to complete the second verification, the process fails and I cannot access my account, even though I have followed all the steps and provided the required information. This situation has been ongoing for a week and is preventing me from using the service normally. I kindly request that my account be checked, the verification problem be fixed, and my access be restored as soon as possible, without any extra fees or negative impact on my account.
