Delay in disbursement of Loan by DHFL & Lodha harrasment for pending payment.

Dear Sir I book flat in Palava (Lodha) in dombivali East in Lakeshore green in month of June 2018. Lodha Finance supported me in getting loan procedure from DHFL Bank and my loan sanctioned in July end for the amount of 45 lakhs. DHFL first disburse amount of 9 lakhs in Sep 2018 and then they disrbuse loan in Jan 2019 for the amount of 18 lakhs. Now from last 3 months we are chasing DHFL to disburse full amount but we dont get any positive reply. as latest news of bankruptcy of DHFL we are not getting proper answers for our query related to final disbursement of our payment. Here Lodha people are keep on chasing us for payment of final amount of 18 lakhs and charging us interest on delay of payment. Secondly DHFL is charging Pre Emi of total amount disburse to us every month which is also additinal burden because we didnt got posession of flat and we are living in Rent flat and paying 16k per month due to delay in loan disbursement and posession by builders. We are confused what next step should we take. Should we cancel flat and ask for refund or should we chase DHFL to disburse full final amount.
