Aircel — requesting upc

Hello,

I want to change my network operator from aircel to airtel due to pathetic network services provided by aircel, so i tried many times to get the unique port code by sending a message on 1900. Unfortunately, i didn't get any response for upc. For past 1 week i am facing network issue in aircel. I cannot make a single call and transaction because i have provided this aircel number to get otp and make my transaction possible. I am stuck. So, kindly do me a favor to get my upc asap.
