Trai — regarding portability of no. from tata docomo to airtel

Address:

Bareilly, Uttar Pradesh, 243122

I applied for number portability ([protected]) on 30/10/2017 from tata docomo to airtel. I took airtel sim on 30/10/2017. Tata docomo signals disappeared in the night of 03/11/2017 but airtel is unable to provide the service. Airtel customer care is responding that this no. Is not in their database, plz contact to your prev. Operator. Tata docomo customer care is also responding the same as this no. Is not in their database.
