$2K of Unauthorized Work Completed by Property Manager

[VB Phom]

Recently, I received a bill for over $2000 worth of work from my property manager. The contract states any work beyond $200 requires notice and approval from the owner. If I wasn't notified of the work and the cost associated with the work, what can and has been done in the past to rectify this? I'm super frustrated and am sure someone in this forum can help me navigate this situation. Or, just share your story to show a little empathy.
