NOTE ON PHONE SUPPORT: We do not post a phone number for Facebook support. If you see a phone number for Facebook support, it is a scam.
Facebook works collaboratively with other companies affected by this type of problem to increase the effectiveness of our enforcement against the groups that promote these scams. While these groups are persistent and work continuously to spread false information, we have taken down a large number of the sites offering fake support numbers and we will continue to do so.
