Aircel — unable to receive porting code for aircel no -[protected]

Address:

New Delhi, Delhi, 110003

Hello sir,
We are facing issue when we try to port out the aircel no, i tried to receive a upc code from last 4 to 5 days, but after sending sms to 1900 i am not able to receive any single response from other side.
Some time network becomes unavailable and some time network available. I have tried to reach out aircel customer care but didn't do that.

Kindly look onto this issue and revert me asap.

Thanks
Ashutosh
