Runwal Group — Delayed possession and extortion of money

I was promised possession in March 2022, then July 2022, then Dec 2022. Now after 1 year of delay CS team is providing ledger of interest charged due to late payments. Late payment interest is charged on booking amount also. Booking amount?? How can booking amount be delayed?? You pay the money and book flat. This is extortion after collecting all monies as per agreement. Have been chasing CEO Manoj Paliwal but no response.
