Idea Cellular — I'm complaining about my idea sim card.

My idea sim is from maharashtra and from past 5 days it's not showing signal. Also it is saying sim card is not ready.
I've tried to search networks, switching off phone, putting sim in another mobile, but nothing is working.
Please do something about this as soon as possible. As this quarantine is going on i can't connect with anyone.
Also my daily data is getting wasted. I've recharged it with three months and now that's of no use.
Please resolve my problem and also do something about your network, as it also doesn't work properly when there's network.
