I encourage everyone to join SUAAWA, you can search for common floor group sovereign Unnathi and then request for membership( you would need to provide documentary evidence to verify your ownership).
Also we should spread the word about this builder, does anybody have friends at print media, we should get this news in papers about the cost escalation demand so that it reaches people thinking of buying other projects of sovereign.
If we all take them to court, they will definitely be screwed.
