I know this may not be a complaint forum, but still I am sharing my pain.
I have used Tata Sky since early 2011. Till last July 30th, 2013 . I never had a problem and I don’t remember calling their customer support in the past. till July end, July 29th, I got a SMS message that I need to change my set top box to MPEG4. I agreed to it and it was changed so quickly, From there onwards, now two weeks over, I am not able to see the channels properly. It is going on and off, every hour. Every day, I call them and a new reference number will be send by SMS. Only once a person came to attend and the problem still persists. I ma facing very bad response from the field customer support team. I am planning to change this facility as soon as possible
