An instruction Freffo runs every day at a fixed time, posting the result.
Steps
Open your Freffo group in WhatsApp.
Type, or say it in a voice note: "Har subah 9 baje jin customers ko reply nahi kiya unki list bhejo"
It runs once a day at that time. If WhatsApp is not connected then, it runs when it is back, up to 3 hours late; after that the day is skipped and you are told.
