Byju's — damaged product

My son waited for the product for about a month patiently and this is what i get for my patience. My son was very excited on the first day itself after the demo was conducted. The content of the product was good but to my disappointment the things did not work the way it should have considering the fact that byjus is a big brand. We have enrolled for 4 years course as i have received good feedback from my colleague about byjus. Hence i wanted my son to try it too.
