the app allows you to report xx-xxxx style messages which seems to be stupid.
the app indicates that some of my complaints were rejected because i had opted in. i cannot believe i opted in for a service that sent me slimming packages. with no proper system to opt out of services you ended up subscribing to for whatever reason... this is stupid.
lenskart,
foodpanda type services would spam you daily with no opt out details in the message or on their website. sometimes i get lucky by sending them a message through facebook/twitter. but not always.
trai really needs to make it mandatory for all of these companies to offer a clear opt out option on their website/app.
