Airtel — refund of amount paid for installation

I requested for airtel broadband connection on 27th of feb, 2019. Guy from airtel called me to make the advance payment of 1767 rupees for 3 month charge and said connection will be done on the same day.

After the payment was done the guy said it will take 2 days. After waiting for the installation for more than 2 days i called the customer care. They said it will be done today.

Its been more than 10 days now. Everyday i am calling the customer care for refund of my money as i dont want their service as installation is still not done.

Kindly refund my amount immediately.
