Amrapali Group — terrace homes

I booked home in 2015 in amrapali terrace homes.
When we booked, it was said that the building is ready. Therefore, you can invest without any worry. And also the builder promised that we will get the possession in 2017.
However, today also the update of the building is as such we saw at the time of booking and it has been more than 2 years.
Nowadays, there are so many complaints and news on the amrapali builder. So, i am really worried on my hard earned money.
Please help.
