Forcefully selling two wheeler parking after possession

My builder has done a lot of illegal things. He has recently issued notice to buy 2wheeler parking and stopping/harassing residents forcefully to buy 2wheeler parking. We have met development authority, SSP, CO, SHO and DM but nothing is coming out. There is no other society in the area where 2wheeler paid parking is being charged. Builder has never informed us about 2wheeler paid parking at the time of flat purchase. Now after 1.5yrs after offering possession and many buyers have done registries also. His employees initially confirmed verbally that residents can park 2wheeler in open area below tower or in their car parking along with car(if it accommodates) as it is being done in other societies. At the time of possession builder given a society guideline booklet where he mentioned that if 2wheeler can be accommodated along with car a resident can park it. but now he is not agreeing to any point. he has already stopped 3 times and it was opened with Police intervention. Plz suggest
