I have gotten an email bill from Facebook and I don't know why since I did not sign up for "Ad Manager" (Which seems to be a system so you can put your advertisements on Facebook. But I do not arrange to use this feature).
I think that maybe Facebook or someone else made a mistake or worse, someone intentionally hacked my account and is having the bill sent to me.
As far as I know, no money is being taken out of my bank account since I have not signed up my bank account with Facebook. But what could happen is if I don't pay the bill (why should I?) then Facebook might take action against me for not paying? What should I do? Just tell them that someone is somehow using my account to have them send bills to me? How do I reach Facebook? There is no link or information on Facebook as to what to do in case of account fraud like this?
Depending on the answers I will provide more information or ask more questions
