Then id move out.
I'd tell everybody who'd listen not to do business with you,i'd report you to the various agencies,launch a civil action for damages and you'd STILL have to fix the window as well as looking for a new tenent.
The attitude that if the landlord doesnt like you he or she isnt beholden to carry out repairs is disgusting.
Not to worry,as more property comes on line they'll all have to buck thier ideas up.
