Expat Properties — expat properties fraud

I have invested in sundew haven1 rowa with expat properties in june 2010. We made 84% (9.89 lac) of the payment of the project within a year by jan 2012 and were promise for registration of the land within 18 months balance was to be collected on registration of the project. From that time we have following as after several email we use to get reply the registration process with soon start. Until 2018 where we were informed project has been cancelled and we can swap for the project. We started discussion for swap. We were promise the interest due on payment collected will be considered but after several follow up no information was given how much is the amount is due in total with interest and later the email discussion for swap or refund also was not responded. Now we have been following but with no response. Finally it time for legal battle to get back our legitimate and hard earned money. I hope the relevant authorities will take note of this. My several friend has also invested with expat on this project.
