Aircel Receiving Message from AIRCEL to pay the due amount even after porting.

Hello All,

I am receiving an SMS from AIRCEL to pay the due amount even after porting the number to another network. Successfully paid the bill for the existing network for nearly 7 months and now i am receiving this kind of message.
Will my number get barred from the existing network if i am not paying the due amount to AIRCEL?
