I have submitted for MNP for BSNL to Aircel on 4th June 2012 for my No. 9445742928. My UPC is BT548332. I submitted this number to aircel office and got new SIM. But BSNL is not ready to deactivate my no. I went to customer care They didn't respond. They told send sms. Thats all we can't do any thing. I tried with 1503. They also told me that we will not deactive your number.
