Hello @ghazanfar,

I’m sorry to hear that you lost access to your Facebook account! Contacting Facebook was the right move, as they can help you regain access. Getting a reply from them may take some time though.

Do you have your Facebook recovery codes? You can regain access to your account by simply entering one of your recovery codes in place of the 2FA passcodes when logging in.

Otherwise, you’ll have to wait for Facebook to reply I’m afraid.

thank you so much mam yes facebook always take time
