I have tatasky DTH comnection for last 4 years . once u purchased it , u have no service support from them . their helpline number are just to cut ur pocket, it goes on long ringing and then transfer of lines and in last the phone disconnected resulting in fruitless deduction of amount from ur mobile. I came across this situation several times.
Once u added any additional pack their is no chance of withdraw it. You can add additional pack on their site but no option of withdrawal. The only option is again the helpline which never responded completely.
There are no service centres information .once u get any technical problem u have no way to rectify. if u ask someone seller, he ask to go for helpline.
tatasky helpline itself need help.
