Byju's — learning app fraud loan

One agent of byjus charged rs. 5000 and sold palm top on 15 days trail base. As this product was not useful for my ward, so i contacted that agent of byjus just after 8 days to return it back. But after first call he didn't pick any of my call and no one ever contacted me to take that useless app back. Now i hv been threaten by capital float fin company to deposit rs. 80000 otherwise they will take some legal action. Recently they hv notice through advocate neeraj k. Sethi mentioning to compromise with the capital float finance company. Main thing is that 'fraudster byjus' is no where in the scene now. Aside tehere call center agents use to call with changed numbers every time and uses abusive language. The agent who sold the product and byjus both are no where in the scene now and this gunda finance company is regularly doing mental torches. How could i get rid of this fraud and threatening.
