Karrm Infrastructure — Possession of my Flat

Hello,
I had booked a flat in 2012, when you had hardly started constructing the building. Its 2021 now and I have not been given the possession yet. Sector has become a Bhoot Bunglow now as nothing has been developed over there since 2015. I had many dreams which are broken by Karrm. Secondly as per your policy I was not suppose to pay the EMI until I get the possession, but State Bank of Maharashtra I dont know what policy they had signed with you that the customers were cheated and were asked to pay the EMI just after 1 and half years of booking the flat, with out giving the possession. I wanted to cancel the house long back when i got a hint about your fake attitude but your sales department gave false hopes and false commitment. Now you please keep your flat with you and reimburse the amount which I have paid to the bank as an EMI for Karrm Infrastructre Pvt Ltd. "You should name yourself Kukarrm" I need an immediate resolution and procedure for cancellation and reimbursement of my hard earn money... Do you understand???
