Cheque bounce

I had taken a personal loan from HDFC bank with 6 months preclosure in 2013 after paying necessary preclosure charges. HDFC asked us to visit the chember branch and submit a blank cheque to preclose the account, after waiting for 4 hours in the branch HDFC staff willfully refused to close the account despite agreed to pay the necessary preclosure charges. Since the account was being closed ESC remittance of EMI was stopped. After couple of months HDFC agreed to settle the matter and in the process of settlement, HDFC deposited a security cheque and got it bounced without informing me and subsequently filed in cheque bounce case in June 2014 without informing or sharing a copy of the complaint. I got a summons in July 2019 and visited the 16th Court and appointed a lawyer by signing Vakalatnama. Since I did not have the copy of the complaint I was not aware of the case number and suddenly Police came home with a NBW. After paying the Pandu they left. Next day I appeared and had the NBW cancalled and provided a copy of Memo to police cancelling the NBW. Please advise how to obtain copy of complaint from the 16th MM Court , is the lawyer on record in collusion for NBW.
