Hi,We purchased Tata Sky connection a month back. We took two connections. one HD and the other non HD. The non HD is working perfectly fine but the HD box is giving problems since day 1. Repeated requests at their call center for rectifying the box has fallen on deaf years. Though the technician has replaced the HD box twice with very old used boxes but none of the box worked for more than a day!!! Infact the third box that he installed stopped working immediately in his presence. TATA sky does not have any service agreement with the customer. The issue is that there is no way you can escalate your complaint as their website gives only one call centre number and one e-mail id, both of which are useless.My advice....keep away from TATA sky
