Passport Office Cochin — Passport renewal

My both parents gave their passport for renewal one year back. My mother received her passport immediately. We waited for my fathers passport. By the time covid 19 cases increased and my father is above 65 years old, so he didn’t go to passport office for inquiries. November my mom detected with cancer for second time and December they shifted to Maharashtra for her treatment. Two days back we got a sms message that his file is processed for closure. We didn’t get a warning message or nobody informed us what was the problem for my dads passport renewal.
