Trai — aircel number mnp not working [protected]

I have tried to change my mobile service provider from aircel to idea due to the network issue in aircel service.
But inspite of trying multiple times for transfer with idea showroom using aadhar online verification the mobile number portability, mnp is not happening. When inquired reason with idea team they said aircel is not releasing the number.

First and last time i got the mnp port code is dt825329 through sms, which is also expired on 10th mar 2018.

Now no where aircel network is available [in chennai and tamil nadu] and its also not connecting to other networks using manual network selection option in mobile.

I request for a solution in this case to retain my aircel mobile number +91 [protected].

Thank you!
