A Federal Bank customer is seeking an interest certificate for their home top-up loan for the financial year 2020-2021, having received one for their main home loan but being refused the former. Despite escalating the issue within the bank and to the Lokpal, their request has been denied. The customer believes a top-up loan is an extension of a home loan, not a personal loan, and has always received such certificates from previous banks. They are now asking for advice on whether to pursue the matter in consumer court.
