rapido booking froud

I am a Rapido bike driver. I received a Rapido booking and accepted it. Shortly thereafter, I received a call from the person who had made the booking. He said, "I am sending you some extra money; please drop the lady off safely." He added, "I am sending you an extra ₹2,000; please return that amount to me." It turned out he was a scammer; subsequently, he cancelled the ride.
