Consumer Redressal

I am customer of TATA SKY . I have subscribed for their mega package. For the past two weeks their service is erratic . We are not receiving more than 80 % of channels. They do not respond to our complaint. Their phone is busy all the time . No person has visited us inspite of lodging complaint. The recorded message on their helpline only says that they are looking at it , but with no result . Even their online chat service is unable to commit any time bound solution . We are helpless . My complaint no. With them is NS 1504044469175. Pl help us getting us a solution and quick response from TATA SKY.
