Idea Cellular — Regular problems in network

I'm using Idea sim from about 6 years. I'm from a village named Dahihanda in Akola district Maharashtra.
Earlier there was not a single problem in Idea network and internet speed but from last one year it seeems like Idea doesn't care about its customers.
There is daily problems in network and Internet speed. If I try to call someone it will take at least 5 attempts before connecting to that person. Same with internet speed as network goes off net get shuts. I'm using 4G sim but most of the time I have to use 3g setting on my mobile for better connectivity. So i[censored] want to provide only 3g connectivity why did u upgraded it to 4g.
I'm a student and in this lockdown phase I have to learn from online classes, so I want u to suggest me some tips on how to use internet when the network if going on and off.
So many people have complained to you but there was not any improvement.
If you don't want take any action then tell us about it we will find some another service provider.
Thank you for reading and please take some action.
Your sincere customer.
