Airtel — postpaid to prepaid conversion issue - please look into this

Hi team,

I don't know who is going to fix my issue but in hope that you may fix my issue i am writing my issue in this forum.

I did postpaid to prepaid conversion on 23 rd dec 2017. On 28 morning my postpaid number got deactivated. Then i inserted my prepaid number and its not getting activated. Both customer care and airtel store is not having any clue what is the issue so i don't know whom to approach for activating my number.

Request you to please help - my number is [protected]
