India Bulls — cheated us with wrong property recommendations

We bought a property with mahavir patwa developers somewhere in thane. 2 bedroom. India bulls assisted in the property purchase and never we spoje to developers. Our mistake. Now the developer is in jail and indiabulls is doing nothing to assist. They have wrongly misrepresented and sold the property to us and we are chasing our refund money isince 4 years to no avail.

Any help appreciarted
Thanks
