I'm sorry, but as of my last knowledge update in January 2022, Facebook does not provide customer support via phone calls.[1-855-974-1389] Facebook primarily offers support through online channels such as their Help Center, community forums, and chat support. The specific support options and contact methods may change over time, so it's recommended to check the latest information on the official Facebook Help Center or contact page.
