Acme Realties Private Limited — Acme Boulevard Tower 5 - delayed possession

Address:

MHB Colony Road, Off, Jogeshwari - Vikhroli Link Rd, Sarvodaya Nagar, Jogeshwari East, Mumbai, Maharashtra 400060

I have booked a 3BHK flat in Tower 5 of Acme Bouleward in Jogeshwari East in October 2014.
While booking, I was promissed a possession in Dec 2017, but when Dec 2017 arrived, builder started siting many excuses and extended the date by a year i.e. Dec 2018.
Year after Year Acme buiilder has pushed the timeline of possession. Last date committed as per Sale Agreement was December 2020 however now we are at almost end of September 2021 and builder is no where near completion of the project.
I have paid almost 85-90% of the flat cos. Its been almost 7 years and now when I asking for the interest or any kind of compansation for the delayed, CRM team says that nothing can be done and you have to bear with us.
