Airtel — Airtel D2h cancellation amount 1274 not refunded

I had booked airtel d2h along with airtel fiber but due to some issue airtel d2h connection is not installed in my society building and got cancelled.

My airtel digital tv id created during booking is [protected](Wakad, Pune, Maharashtra)

I have contacted twice with customer care and salesman but no one is refunding my amount.

Customer care is saying salesman will refund your amount and salesman says airtel will refund your amount...but ultimately I am not getting my amount back.

Please help me to get my cancellation amount back.
