We have to regularly check the subscribed channels, I have paid for channels which I never subscribed, no response for complaint mails, worst response from customer care executives, for No signal they started explain me the parts of their setup box, it has cable, remote, so many parts inside it, etc.
By subscribing to it we are suffering a lot. Please avoid Tatasky, till now our no signal problem has not been fixed, till now made 8+ request mails, talked with 2 customer care executives, all waste please avoid suffering like me.
