Aircel — not able to get upc code for porting out

Address:

Khordha, Odisha, 751024

I have sent many sms request to 1900 for porting out of my aircel no [protected]. But did not get any codes. The aircel network is fluctuating and their customer care number is not getting connected. Then how to get the code and port out. I can't lose this number as this is my primary no and important as well. If you are closing your services then atleast help your customers to retain their numbers. This is so unprofessional from aircel. Worst service... Help please....
