Trai — I am complaining about the service of tata sky non delivery of selected channels

I am a customer of tatasky dth. I had applied for some channels as per their directions given in the web site. But today they are not giving the channels i requested and hence this complaint. I am a resident of kottayam and a customer of tatasky. Please do the needful. I had already paid for one year subscription.
I cannot contact them by their e mail address also. Pleasee do the needful.
