Reliance Digital Tv — booked reliance digital tv but not received

Address:

Gautam Buddh Nagar, Uttar Pradesh, 201301

I have done pre booking for reliance digital tv - big tv on 6th march 2018, they promised to give the connection in 30 to 45 days, but it's more than 45 days now, no connection done.
Contacted many times to customer care they don't speak properly, mails not replied, tweets also ignored.
As a customer i want my 500 rs returned back.
I appeal all to file complaint to consumer forum n forward this matter to media by all means.
