Well you've convinced me, but unfortunately I'm not the person you need to convince, hence the thread.
Are you in talks with the developer? i mean, is he contactable and does he respond, or is he in hiding somewhere?
Do you currently live in Dubai? and have you been to see him personally?
I think you mentioned in another thread, about trying to talk to him, but he just keeps refusing to co-operate at all, and will demand more cash on schedule
(is that you?)
I think it's obvious by now that we can't rely on RERA, or anyone else as yet, they are just over-burdened and, from most stories, not overly interested either.
You need to look through all your past correspondence and see if he's told any outright lies, or false promises, or tried to get you to sign any "false" documents about escrows etc (I was asked to sign a second "reservation form" 6 months after the 1st at a 40% reduced price.
I refused, saying I would be entering uncharterd waters with that, and i brought up the subject again, with the fact i still had the e-mails, when i was looking for refund.
Even if you find anything, you then have to hope he considers himself as having some reputation/ respect which he doesn't want to damage.
He may not care, or just be past that point.
