I have had the worst possible exp. I bought an additional connection online, they promised to install the same day, had to make 10 calls to get it installed, when installed, there was a an issue, the technician said it will take 30 minutes to activate and since I had another connection, did ask him to go, only later did I realize it was a faulty box, because the minute I had called them for technical support, before I could tell them the issue, they said the box had a problem and there was no boxes in stock.
I have paid them in advance and not sure if they will refund.
Please DO NOT BUY TATA SKY.
