Neptune Group — Regarding not giving any response about the construction and booking

Hello I am Dr Abhay Sharma, I have book a project with Ramrajya in 2018 and paid the booking amount and also the stamp duty/registration fees and the GST amount.
previously at the time of booking they were giving prompt response but now they are worth of nothing.
they are all just money eaters who have taken our hard money and not giving any response now.
Till date they are not giving any progress on the construction of the project or when they will start.
whenever we call them they will ask for money our money is not on road to give them.
Are they going to start the project also or not that also no idea.
Now when we call they just say no funding
they have just looted the hard money of the poor peoples.
