Vatika Group — vatika turning point project delayed

Address:

Vatika triangle office MG road gurgaon

In sep 2018 i booked a 2bhk flat in vatika turning point project.
Promised completion date is may 2022
But they continue to delay it with out a single information.
Now taking advantage of corona situation they are saying it will be more delayed or even cancel.
Now they are saying they have two option only 1. Shift to other under construction property and pay more money.
2. Cancel the deal : in this case it will take about 1.5 yrs to refund and even deduction of 10% amount.

What to do now, i want all of my money back.
Need help
