I am using TATA SKY dth since from last 11 years . And till today not a single complain. Tata sky is the best brand for DTH services. Its picture and sound quality is awesome and same always in any climatic situation cloudy Raining Fog etc.
Tata sky also offer one month free Channels if bill paid all together for current year. But there Regional channel list is limited which I dislike. Tata sky website works properly and secure. I always use it to pay my bills.
There are many plan in there list one can subscribe any plan according to his taste and budget.
So I recommend it to others.
