No maintenance by the Society

Hi I am Vilas from Mumbai, I am a member of housing society with a flat on first floor. Problem is that there is a tin shed put by flat owner on the ground floor which surrounds almost 90% of open area around my flat . This shed accumulates lot of garbage and waste( really bad waste including used condoms and sanitary napkins etc) thrown by top floors. In spite of repeated complains and reminders the society is not doing any thing to clear the waste including regular cleaning. Only on occasion of Diwali the cleaning is done by the housekeeping of society that to for collecting bonus there after no cleaning happens, I wrote a letter telling them I will be stopping payment of maintenance if the same is not cleaned on regular basis. In reply the society has written to me that they have inspected the area and they found nothing the shed is clean . This is a total lie the shed is still full of waste and garbage. When I asked the Manger to come and check the shed in my presence he refused to come on the pretext that he is busy. This shed according to them is unauthorised and they have issued a notice to the flat owner on the ground floor for removal of shed but nothing is happening for the last one and half year. in the meantime Dengue threat was detected by BMC during pre Diwali inspection don by them.
