Builder related

I am residing in this complex in Gurgaon since 2006. Till date the builder hasn't handed over the complex to the RWA. He charges maintenance at the rate of Rs 3/- and hasn't given the accounts from the date of inception till date. The complex doesn't have the occupation or completion certificate. There are gross irregularities for which RTIs were filed but DTCP panchkula hasn't responded. We are paying house tax to MCG but we do not have municipal water etc. There are very many deviations in the building plan. These are a few things I have spelt. Kindly let me know if we can file a case with HRERA against the builder and if someone can assist us.
