Great, I'd also like if the merchants were forced to not message via WhatsApp; From couriers to securities every business in India expects that you have WhatsApp and are willing to communicate with them through it.
I just tell all of them that I don’t have or use WhatsApp, and that’s true. They wouldn’t be able to send anything over WhatsApp since my number was never registered with that platform. Those who want my business will have to abide by my preferences.
I've had customer service personal change their tone towards me after I tell them that I don't use WhatsApp and requested them to send an email instead, They seem to take it as a personal insult (or) Couldn't believe that someone couldn't have WhatsApp.
