Aircel — issue in mobile number portability from aircel

I was trying to port my number from aircel to other network and i even got the upc code for porting. But when the other network tried porting, it got rejected. Now the issue is the porting code got expired and i do not have the signal to send any sms and i tired calling from other networks to generate upc over call but it's not working even. I am using this number for long time and was using it in my day to day life. I do not want to miss this number. Please get this resolved asap.
