In the month of July 2015 I ditched our Tatasky which we were using since last 6-7 years coz at that time Airtel had more HD Channels and package pricing looked more sensible then Tatasky. Also, we were using Tatasky DVR since 2009 and when I call'd CC about upgrading to HD DVR, he informed me that I'd need to pay 6k for the upgrade. At that time, new Airtel DVR @ 4440/- online seemed more VFM deal to me and see now what happened.
I guess Airtel proved ki "Mehenga roe ek baar aur sasta roe baar baar"
