Why can't renters get property managers to promptly fix repairs and treat wear-and-tear disputes fairly?

“Real estate wants me too pay an invoice that I disagree with”

“Is my property manager being petty asking for these bulbs to "match"?”

“Real estate agent failing to organise a fix for bathroom leakage for over 3 months and continuously asking for money to pay for plumber inspection and a handyman fix the issue. What complaint options do I have?”
