Swiggy instamart had a crazy offer (or glitch)

Im a student living in hostel and many of my friends and me got around 5,000 to 50,000 free cash. The offer was valid only for 5 to 10 mins. Idk if everyone got it or why nobody is talking about it. We order Earbuds, smartwatched and speaker and got it for only 9 rs. Did ya'll get this too?
