Airtel — Deficiency in service

Address:

101 santhome high road Chennai 600 028

We have a smart phone with prepaid connection No [protected] for the last several years with Airtel in my name p.sathyanaraysna rao s/o late Mr. Vittal Rao.
The sim card of the phone got corrupted when we downloaded soft ware update from samsung phone itself
We approached the airtel shop next to soorya hospital on arcot road Chennai and and got a fresh sim card. We were told to insert the sim after 4 hrs.
We loaded the sim after 24 hrs and found that the connection was not activated even after 24 hrs.

We approached the airtel shop again to enquire about activation and they told us they cannot do this because of name change.

The sim card name on their system had been erroneously input as vittal rao my father instead of my name which is Sathyanarayana rao. My father is no more.
We told them about the input error on their system and submitted adhar card for second time to prove my name and my dad name.
They refused to accept the details on original adhar card and said they cannot activate the phone on the basis of a govt. Document.
Why should the phone holder should be victimised on the input errors committed by the company
Then they told me to carry my brother who is the owner of the phone. He is almost paralysed, cannot walk still I told them that we will bring him in auto.
Again they refused and told us it will take weeks to set the mistakes corrected.
There is an urgent need for my brother to talk to his doctor at valasaravakkam and consult about his medication on regular basis. In the absence of the phone he is unable to do this

Under the circumstances we need your help and intervention and resolve the issue with Airtel in activating the smart phone
