They closed my plumbing ticket as 'resolved' before anyone showed up

Shower drain backed up completely, water standing 6 inches during a 5-minute shower. Filed ticket Monday. Tuesday morning: got an automated 'your request has been resolved' email. Nobody had come. Called the office. They said 'maintenance marked it complete.' Re-filed the ticket. Same thing happened Wednesday. On Thursday I knocked on the office door in person. Drain was fixed by Friday. Always follow up in person.
