Puneet Duggal and Sorabh had bought Marriage Clothes (Coats) . However puneet's coat was not working and puneet duggal got caught inside it when his photos were clicked during their marriage. It's clear that even Krishan Lal Duggal was wearing coat gifted by us during whole mohabbatein movie, so it's strange why their son bought trouble for himself Probably those people were looking at sorabh that his coat is working, but the problem is that sorabh works also unlike puneet. The coat was located at a location in pakistan with puneet duggal(a bala) trapped inside it and was destroyed by the airstrike to extract puneet duggal safely out of it.
However it's sad that puneet didn't begin to work at all and that bakra of lachcho's marriage was eaten up as well at prem's much time later.
