DCB Bank — Complaining About Reduce Gold loan OD Limit

MySelf SANKET SHARMA My Account No.[protected]. This account exist in Majitha Road, Ghala Mala chowk, Amritsar Branch. I have taken OD Loan limit against gold in January 2021 and i always serve monthly interest on time but January 2022 onwards DCB Bank reduced my OD limit from 90% to 75% without any prior intimation and my consent.
Please share reasons for reducing limit although I have been making my interest payments time to time.
I am being pressurized by bank to pay the difference amount but I am not in a position to pay due to family obligations.
