Society formed by builder 3 years back but not handed over to members yet due to his dues

Dear Sir / Madam, I Mr. Vinayak H Pandit staying in Mumbai. I bought resale Flat at Karjat in 2014, also paid 2 years advanced maintenance for the same. After 2 years builder has increased the maintenance charges from 1 Rupee to 3 Rupee/sq ft , also adding water charges (3-4 Tanker daily / 900/Tanker) without informing to anyone. Now Maintenance came approx Rs. 2000 / month for 1 BHK. I have not paid any amount after 2 advanced maintenance due to charges increased without informing anyone and even no one allowed him to continue Tanker Water, since there is NagarPalika provided few Water which is sufficient for members who are staying there, also he used Tanker water for his other buildings but he is denying the same. Last week we did meeting with Builder for Society handed over but builder said that I am not going to handed over the Society till my dues are not cleared which as below. Member Maintenance - approx 5 Lacs Other Charges for 2 Years - approx 1.5 lacs (Audit and other charges) Builder Dues - Approx 6.5 Lacs Water Tanker Charges after 18 Months are 9 Lacs which he put into Members Maintenance. I am ready to pay Maitainence charges as per agreement but Builder not ready to take that. I need advice what I do next also can Members take society rights without involving builder / builder dues ? Is it necessary to pay Builder dues before handing over Society ?
