Tata Housing Development — refund of 1 lac

I booked a flat from tata housing at new heaven 2 boisar (Unit t11- g06). There was payment of 1 lac, where it was requested not deposit the cheque and keep the cheque on hold till i get confirmation from the bank if the housing loan is being approved or not, my loan did not get approved due to the existing loan which i have, hence requested tata housing to refund the 1 lac back to me, where their refusing to refund the money back. I have also raised a complaint with tata team and informed them i had call and spoken to constant person (Pankaj) who i was dealing on site that not to deposit the cheque and hold the cheque and i was informed by the tata team that they don't take any verbal communication has valid evidence. I would also like to bring to your notice that after repeated requests to mr. Pankaj your sales representative not to deposit the cheque before the loan amount was approved, he took no heed to my requests and without my knowledge deposited the cheque in to the bank account a sum of inr 1, 00, 000/- (One lakh rupees) which has been debited from my bank account and credited into their account. On multiple occasions i was promised that the whole amount would be refunded to me without any question asked if the loan was not approved. However, i have been mis-sold to and fraudulently being sold the flat just so that they could meet their sales target. I will not accept such fraudulency with my hard earned money. I request you to look into this and make sure i get back my money.
