Reg:the Parking issue

Hi Sir, I booked a property in july in Pune PCMC area in Dudulgaon pune. at the time of Buying the property,builder included the Covered parking charges of Rs. 2 lakh in total cost. which I paid to builder. I got the possession of the flat on 1 October 2017 and its almost 8 month but builder has not provided parking to me even after repeated request to him but has allotted parking to some of the flat from the last 1 month,the surprising thing is I did not get to know when the builder started allocating the parking as builder did not inform me,I only get to know when I seen the 2-3 flat number plate on the parking then I contacted the builder regarding the same and he told me that he is allotting the parking on first booked-first allotment policy and only contacting the people who he is allocating the parking and hence didn't inform any one else and told me that your flat booking number is 76 so when your parking number come we would inform you and at that time whatever parking is available he would let me know and I can choose from available parking but he has allocated most of the parking now(good ones which I wanted) and when I contacted him recently regarding my parking he told me that he has hold the parking allocation for 1 month and would let me know once he start ,the surprising thing is some of the parking I can see is not allotted and when I asking for that parking he is not ready to give me(I guess,reserved for his own people) but told me I can choose for any parking other then that which I don't want so my question is : 1: as per RERA how long builder can take to allot the parking after the flat possession?? 2: can he halt the parking allotment without informing the flat owners like me??. 3: he has not form the society till now,how long builder can take to from the society?? 4: whatever parking builder allot me if I am not satisfy with it what option I have as per RERA against the builder. PS:I bought a car in november 2017 and not getting any parking for it and request builder to allot me the parking but still he is not listening as according to him he has hauled the parking and allocated all the good parking to almost 20-30% or more to people.my car is also got damage due to non availability of the parking but builder is not taking any responsibility for it.
