Aircel — aircel upc code generation

Address:

Jaipur, Rajasthan

I am trying from last 5-7 days and already sent lots of messages to 1900 for port but there is no reply from your side regarding UPC code
I have also my 20 digit sim card number but still there is no solution to port my sim
I have also called customer care many times but no one is receiving the call
even all the aircel shops and offices are closed
So tell me from where I can port my sim card so that my number will remain same otherwise if number would be closed then it will create a big problem for me to update my new number in various organisations
Please provide UPC code as soon as possible
So that I can continue with my same contact number..
