Tata Sky — tata sky duped me of Rs 2050

Address:

Mumbai City, Maharashtra

I have booked tata sky connection day before yesterday (16 April 2015). While I'd been promised a connection the very next day, I didn't receive it. My calls are all unanswered. I'm put on hold for more than 20 min by Ivr itself and my calls r later disconnected, I requested for several call backs but I'm yet to receive any calls. While I wanted to book a new connection they flooded me with calls. After receiving the payment (mode:credit card) they stopped responding.
