Broken chamber

Neighbor’s broken chamber gushes out mess and stores water in front of my apartment. Landlord said ‘some people are owing him, so he can’t fix it’s. I am not owning him. Paid 200k for rent and 20k for maintenance. I pay 20,000 yearly for maintenance but nothing is done. Apartment in total mess. This house is located in Higher Ground Estate, Sangotedo, Lagos. This is so unhealthy and no one can talk to my landlord because he is influential. He says ‘no one can teach him how to run his house’s.  He is the eastate’s chairman.
