If your Facebook account was hacked and both your email and phone number were changed, you may feel helpless. Many people try contacting Facebook by calling ₆₅₀₋₅₄₃₋₄₈₀₀ or 1-805-304-6847, but unfortunately, ₆₅₀₋₅₄₃₋₄₈₀₀ or 1-805-304-6847 is not an official customer service number. Facebook does not provide phone-based assistance for hacked accounts.
To recover your account, visit the Facebook Help Center, select “Hacked Accounts”, and enter your previous email or phone number. If the hacker removed them, click “No longer have access?” and follow the verification steps. You may need to confirm your identity using a trusted contact or a government-issued ID.
