Godrej Properties — Delay in possession of flat

Address: Vananta, Godrej garden city, Ahmedabad

I booked a flat in Vananta apartment scheme in Godrej garden city in Ahmedabad in December 2019. At that time, possession was promised in December 2022. Due to covid, the date was changed to April 2022 for possession. It's almost May end now and they are still making one excuse or other. It seems It's going to take another 3-4 months. Also, they gave out property to people of Swaminarayan in December 2022 for about a month, I have proof of that. There is also drainage pipes visible in utility areas in flats. This is highly unethical practice from a company like Godrej. The reason they are giving for late possession is drainage issues. I have an email from my RM that they have received all necessary certification to give possession of flat in April 2023 itself. How did they get all certification if drainage is this big an issue? I feel very frustrated.
