Grahak Setu is a mobile app meant for consumers to use with which they can connect to manufacturers like you. To log service complaints. And track service complaints. And receive itemized estimates, GST invoices, and even make payments online. More here.
So let us say, as a customer (Grahak), you own a Microwave oven from Samsung, a TV from Sony, and a Washing Machine from Bosch. You can connect to each of these companies from the same profile in the same app. But of course, Samsung will only know that you own their Microwave oven. As Sony would only know about the TV.
