Raheja Developers — non registration of flat by raheja developers limited

Address:

IRC village, N3 105, Gurgaon, Haryana, 751015

I have purchased a flat c 504 in raheja atharva project by raheja developer limited (Rdl) in sector 109 gurgaon. I have deposited the complete stamp duty fees to rdl in the year 2016 however till date i haven't got any news regarding the registration of my property till date. I have sent many reminders regarding the same to rdl at their customer care mail address however they have only sought time extension of few months each time.
