Idea Cellular — high ping and zero download speed

Website:

vi.in

I've been using idea sim since 2016, and till march, 2020 everything was fine. But from the month of april, 2020my online classes started and i don't know wether its coincidently that from the same month, the network quality deteriorated too. I get disconnected from my online classes regularly cause of the bad network (Note that i live in the city, not in the countryside or any village). The download speed is really zero and the ping is very high. And not only in my class, wether if i'm browsing the net or playing any online game, i always end up being frustrated from the bad network.
Even after vi merged and formed a single entity, the problem persists.
I request the officials there to look after the problem. Or else i would shift to any better network provider.
