Aircel — not getting upc code for porting

Address:

700047

Dear sir. Im a aircel prepaid user want to port my no to other network but ai have sent porting request to 1900 more than 5 times. Still im not getting the upc code... This no is very important to me... I want the problem to be resolved soon. Im aircel user of west bengal. After filing the bankruptcy of aircel this same porting problem happens to all customers of aircel. Trai should take care of this matter. If a company is bankrupt now customers of that company are being punished?? Strange about the administration of trai. Not at all looking up in this matter.
