You're not the only one who can't get a problem resolved after hours and hours on the phone.
Their customer service is a joke. "Team of experts"?? I haven't spoken to one yet.
Have you tried Facebook's customer service specialist team called T-Force?
That's a lot of time to spend on a call. Sorry this happened to you but we want to make sure we help in anyway possible. We can offer some help here on support if you tell us what's going on. T-Force is a great group that can assist with most issue as well.
