Initial Stages and false minutes

this is a NSW question. Only 2 units in a block of 14 have been sold. Both these hold 7 % entitlement. The Developer has a unit he is keeping with a 15% entitlement and has 11 for sale. 5 with 7% entitlements and 6 with 6%. He is now wanting to charge myself and the other owner 1/3 of the water use charges from the day we each moved in he has set a levy then changed his mind and raised it by $500 . We have never seen a financial statement, nor held an official meeting with agenda and minutes. He tells us he has the majority vote and will make all the decisions until 2 more units are sold.  He has now told us we are at ” war” with him as we will not pay him the money for the water. We have never seen a water invoice. Any clues what we should do.
