Airtel Dish TV — Advance payment taken, not responding

Address: 2-24-78, Venkateswara Nagar, Rajahmundry

Yesterday, I received a call from Airtel DishTV regarding new connection and asked to pay amount of Rs. 2000/- through PhonePe, I paid the amount, later the phone is switched off and when I call Airtel Customer Care, they are saying that they have not received the amount, how can I get back my amount.
