Victim of gda5 gawadar scam

I had bought a plot in gawadar (gda5 scheme) in 2005. I made all payments including additional payments for development costs. However, after 12 years, there is no actual development and I have not been handed over the plot. Project developer (taloo builders) is being deceitful and is not responding either.Last i checked, the builder’s noc with gawadar development authority had expired as well.Can someone help me with whichever the options i might have? How can i connect with other victims of this scam so we could take a legal action?Thank you Ahmad
