Confident Group — Confident gardenia

Hi team, i bought a plot at gardenia project, (Sarjapur, bangalore) from confident group in 2012. At the time of purchase, we were offered many facilities and was promised the completed project will be handed over by 2014. It has been 8 years since they launched the project and there is no response on completion of the project and least to be said about the responses we are getting from the confident group.
While we (Around 300+) owners were kept at limbo, they were shamelessly launching new projects and continue to cheat unassuming clients of their hard earned money. We feel like our funds are doomed and we are kept under compete darkness.
