I am having worst experience on after sales service by Tata Sky.
I selected Tata sky despite of costliest DTH service provider with the expectation to get good service, but I was proved to be wrong.
Whenever you will order any replacement of box/remote, first of all, they will never it have inthe stock.
Then, they will never come back on the update on your request.
You just keep calling to the help line no. but it is useless.Everytime you will get an assurance but no action.
I would advise, no one to go for Tata sky.
