Reliance Digital — reliance big tv pre booking

Address:

New Delhi, Delhi, 110016

In the month of March 2018, Reliance Big TV launched a scheme through large advertisements for which the booking amount was Rs. 499/-, large number of peoples like me booked this scheme and paid the amount. I have book on 02/03/2018, As per promise the connection was installed within 30 to 45 days but even after passing more than 140 days no connection has been installed. I have made so many calls on their call centre ask for refund but they are not giving satisfactory reply.

Its not happen only with me. In the name of Pre - Booking Reliance have collect 499/- from million of people but they are not installed a single connecting after 140 days. Its big scam. Reliance cheat million of Indian People. Kindly look into this matter.
Kindly do need full
