Idea Cellular — Idea Cellular network is showing emergency call only for my number

From yesterday, my idea cellular network number is showing emergency calls only and I'm not able to call or do any bank transactions due to this as sms and all services are blocked due to this I'm not sure what happened exactly but whenever I'm searching for available networks it's showing IDEA 4G but while connecting it says can't connect to this number. I'm having only one number and due to no service it's causing me lots of problem Request to kindly register the complaint asap and resolve it
