Parking Space Allotment by the Builder

Greetings Sir/ Madam, We have bought a flat in an apartment. In our apartment 10 flats each having 1640 square meters including common area. The builder has allocated a car space for us. The parking spaces alloted by him are not in order I mean starting from 101, next 102 then 201 next 202, 301, 302 like this. Randomly he has allocated parking spaces showing favourtiism where there is no equality of the space for all residents. the builders didn't sold one flat and kept it on his name . now he is residing in the apartment itself. He is saying that totally apartment have 12 parking spaces in that he owns 3 spaces and other 9 spaces for all residents who have bought the flats. He is also saying that he will sell the 1 parking space to one of the resident for 2 lakhs. and rest 2 spaces he will keep for him as he is having 2 cars. We have got very small space which we couldn't able to park our seven seater vehicle. I am mentioning the issues again, random allocation of spaces, in eqauality on distribution of parking space and keeping the builder 3 spaces for him, selling one of his space space to the resident. His behaviour is too rude making every one keep quite, please guide me on this , I am from Nellore , Andhra Pradesh.
