Supertech — supertech capetown - unethical dish installation practices

Address: Sector-74 Noida, Gautam Buddh Nagar, Uttar Pradesh, 201301

I have recently shifted in supertech capetown. I am an existing invested videocon d2h customer. Supertech captown (Noida sec-74) is not allowing me to continue with my videocon d2h connection and is forcing to take up the tata sky that they are centrally operating. Moreover, the tata sky being operated is costlier (Rs. 1800 for new connection) vs the outside tata sky connection offered directly by the company (Rs. 1500)
I would like supertech capetown to allow me to continue my videocon d2h connection and allow me to install the dish tv on the terrace.
