Airtel — airtel broadband connection amount not refunded

Address: Bangalore, Karnataka, 560037

Airtel took 1000 for new broadband connection and did not provide connection telling that connection is not available in my area. After multiple followups i provided required documents to refund the amount to my bank account.
It is more than 6 months completed since i requested for refund and no refund happened yet.

Below is my connection details:
Caf no.: rtblr7332316
Transaction id:[protected]

I have raised online ticket to airtel for refund with ticket id: aorbad45d.

Below is the latest update i got from airtel team
(I have registered your request for refund of rs. 1000/- and the reference number is 86466932. Let me assure you that the issue would be resolved within 6 days.)

Please take necessary actions on airtel for this behaviour.
