Taking to Twitter, Grover wrote, "WhatsApp Pay has to be the biggest failure in India as a tech product.

The ex-judge of business reality television series 'Shark Tank' India also shared a screenshot of WhatsApp's advertisement in the tweet's comment section and said that the firm should have invested on improving the payment services instead of posting the ad about it safety features.
He wrote, "Yeh ad hi dekh lo - iska kya acahar daalega koi customer - itni ad WhatsApp Pay ki kar lete instead. Public policy uncle aur vakil babu dhanda chalayenge to aisa hi hoga."
