Airtel — Complaint regarding phone Number deleted

Address:

Mawkyrwat-793114

My airtel number [protected] has been deleted, it is a long time use sim card since i was using aircel, after porting from Aircel to Airtel i regularly use this number for so many years but suddenly without any notice message or call they directly deleting my number from Airtel service, i had requested to Airtel office to get back the same number but they told that the number had been deleted from the Telecom due to mismatch or insufficient documents... I this regard i request to please help me with this matter as the main balance Rs 5000/- and three month pack is still available with this number.
