Not giving hand-over of my flat even after 7 month

Review on Brigade Buena Vista, Budigere, Bangalore

I booked a ready to move apartment in Brigade Buena Vista(Ph-II) in May 2022 and They have promised to handover in two months. I have paid 96% of flat on 15th July 2022. After receiving payment, they have started saying that they can not do registration as there is some issue with e-khata of my booked flat. They are liaising with Panchayath office for getting the e-khata and it will be received within 1 month, thereafter registration will be done. But till date, it is almost six months they are saying that e-khata is under process and they are working on it. Every time I call them at their call centre, they give exercises. I am totalling frustrated with this builder. Their CRM team do not care about customers after getting payment.

Can anybody provide contact No. of their higher management?

Can anybody provide suggestion what should I do now?
