Family Credit — Loan of two wheeler

Address:

380007

I have submitted total 18 cheque towards loan taken by me. Yesterday I went to family credit ahmedabad branch at third eye building to get n.o.c certificate as a proof of my loan completed.they are showing that 750 rs to be paid as a cheque bounce in January 2016. So I need totally in detail.and also need reason behind why the cheque bounced because I never got back that bounced cheque since January 2016 and you are charging 750rs of penalty for one cheque bounce which should be 350rs.
