Not the victim but your chance as the owner - most likely have to top up the price to get another developer/contractor to complete the project.

Look at Platinum Ara Damansara - now known as Maisson @ Ara Damansara, that will most likely the be solution for the abandoned project buyers.

What was the last certificate of payment from the Architect? Up to which stage ?

Also have the same thought. Tan Sri Gan of PV seems to be people with social responsibility, highly unlikely PV will abandoned their project.
