Excitel — Frequently disconnection internet from 3 days

Hlo sir
My name is gourav babu. I have been contacting excitel customer service for 3 days. But I am not getting any good response from them. Everyone is telling me the same thing that turn off your router, turn on. Just do nothing else. He simply says that we also have to press the connection on our behalf. But not yet, I did not get any solution from anywhere. It's been 72 hours complete to going their connection, but whenever I speak, the only thing they get from their side is that our team work should be done by our team sometime. Neither have any of their agents been contacted yet.
I am a student and on YouTube as well, I am having problems on both sides. I have not been able to make any video since 3 days, nor am I able to join my online classes only and only because of no internet. I have screenshots from all the recordings as well as when my internet has gone and when I have spoken to the customer service. I do all these things below
