DCB Bank — Less payment of FDs on maturity

We deposited one FD each in the name of Ravinder Kumar Rohilla and Asha Rohilla in DCB Bank, MG Road Bangalore. These FDs matured on 13.1.23. On maturity the deposited maturity value in my HDFC Bank. We found that they deducted Rs.21024 from each of our FDs. On enquiry they are unable to give any satisfying reply. They are not able to provide Form 16A for the last quarters of FY 22-23. We are put to lot of harassment from maturity. We are Senior Citizens and they don't bother for it. We request to register our complaint and take it seriously.
