Idea — No network

I am from ahmedabad and i am using an idea sim which works perfectly but from 1 day it shows no service available and no tower available because having 1 sim i can't call customer care

I tried
1. Turning on and of airplane mode
2. Restart phone several time
3. Change sim to another slot even changed the idea sim another mobile

I am very dissapointment with idea i had done recharge for 84 days and still i have left 60 + days
