Galaxy Pine Court — 3+ years delay in handover & no communication to customers

Website: galaxyhomes.com/pine-court

I have bought a 3bhk property in galaxy pinecourt in 2013 with agreed handover date in 2016. There has been 3 years delay in handover which was not communicated to me by galaxy team, and now when i reached out to them i hear that there are further delays. They still do not have a handover date. I would like to have a compensation for this immense delay. They dont care to respond to emails and calls. Extremely pathetic behaviour towards customers and zero professionalism. More details below -
Date of handover (As per contract) : apr 2016
Client number : +91-[protected], +91-[protected]
Description sumary : 3+ years of delay in handover the property and absolutely no communication of this to the customers. They still do not have a handover date
Desirable resolution : rs.15, 000/- per month from nov 2018 to the handover date to be paid by galaxy to my account as a compensation for the delay
