Idea Cellular — No network since morning no net since past 15days

My sim card is not showing any network since today evening, 4g is not working since past 15days in a row
I tried to solve the problem by restarting the phone, reinserting the sim.
Also everytime someone tries to call me it says invalid, after 3 consecutive dials they are able to reach out to me. Pathetic service. Where as I have another sim of idea which shows full network

On checking with customer care, they tell me that all the services are active in my number but i don't see any network signal.
I have lodged a complaint s[protected] but i cant see status because they send a verification code the same number. How can i receive a message when i don't have any network.
The attachment which I have attached in it also its clearly visible that there’s no network.
