Aircel — my mobile number is stuck with aircel

I'm one of the customers of aircel. I'm using it from the past 10 years. It is my permanent number, i have given it to every certificate which needs a mobile number for example in banks, aadhaar, pf, otp's for credit card, e-pf, uan, bank statements anything i do or i need comes to that number only. I need that number so badly. I'm unable to port from this network and i'm not even able to get the port code as it is showing no network. Please help me.
