Airtel — airtel sim not activated from last 96 hrs

Hello,
I have purchased airtel sim from amritsar, but it is not activated from last 96 hrs as airtel office staff committed me that it will be activated within 24 hrs. Yesterday i again visited to airtel office they said we forget to process and still today it is not working.

Is this is the customer service provided by airtel company??

This is very pathetic!!!

Who is responsible for the inconvenience caused to me on daily basics???

Is there any revert or suggestions from company sides??

Will any appropriate action will taken against that staff members so anyone other couldn't face this harassment??

I will wait for the reply... On my mail jassie. [protected]@gmail.com
