Delay in sales dead / Land Registration

Dear All, I booked a plot on April 21, 2024, in the Megapolis project through a broker partner and completed all payments by May 5. We planned to complete the registry on May 10th, Akshaya Tritiya, as it is considered an auspicious day. I paid for the registry stamp paper, and the builder prepared the sale deed. On the scheduled date, I went to the Dadri Tehsil for the registry. Despite following up throughout the day, I was informed in the evening by the developer’s team that the signing authority was unavailable due to an emergency, and they requested a postponement to the following week. To honor the auspicious day, they advised me to visit their office to sign certain documents, which I complied with. Please note that this project is under Ansal API, with Sarvottam Group as the sales partner. Since then, I have been persistently following up with the builder, but the registry has been repeatedly delayed. My signed registry stamp paper remains with the developer’s office. I have all the required documents in place, including: Application Form Agreement (BBA) Payment Receipt No Dues Certificate Possession Letter Could you please advise on the next steps to ensure the registry is completed promptly? Your guidance on how to proceed with this matter would be greatly appreciated. Thank you for your assistance.
