Unisyn Enterprises — refund not received for unavailed tata sky installation

Address:

Ranga Reddy, Andhra Pradesh, 500019

On 24/02/2019 a sales girl visited my house and told that they are giving tata sky connection worth 4500/- at just 2015/- if pad through paytm for existing non tatasky dth customers who has qr code on there aadhaar cards. She also told that monthly hd telugu package is just 250/-. So i paid 2015/- through paytm and applied for connection. Later on same day i called tatasky helpline number and realized that 2015/- is the same amount that they offer for any customer and hd monthly rental is around 450/-. Immediately i asked that sales girl who is till visiting other flats in our apartment to cancel the connection, she told that refund will be received within 21 days. I am waiting for the refund from one month.

I request unisyn enterprises to refund my money as soon as possible.
