Airtel — refund of activation fee of inr 500

Address:

Bangalore, Karnataka, 560037

Hi team,

On feb 2018 i paid inr 500 for broadband connection in my area for 40 mbps plan, but after some days airtel people said that they can't provide 40 mbps plan in that area, so i asked for refund. I'm still waiting for my refund money but no step has been taken.
I have already raised complain that has been closed, please take the necessary steps.
