Tata Sky — not able to view any sports, english news, english channels and HD channels

Hello, My subscriber ID is [protected]. I have paid 6500-00 for Grand sports for one year + HD channels. As of 3rd March I am not able to view any of the above channels and sometime there is absolutely no signal at all. I have sent emails to tatasky helpdesk but there is no response. Can you please let me know when I can hope to be able to see the channels. For the days there has been no service are you going to extend the number of days or do we have to pay for your inefficiency. Also do let me know what is the recourse to getting my money back. This kind of apathy is not acceptable. I have nowhere to turn to with all your help lines not getting through and no one from your dealer network seems to know what is happening and say it is a company problem and they cannot help. Would appreciate if you can either resolve it immediately or return the money for the balance of the year.
