[Resolved]  Dish TV — Unsolicited SMS

Dish TV keeps sending annoying SMS on my mobile. There website does not have
any unsubscribe registry. My question is:
1. Are they bound by the supreme court order to maintain a do not
call registry ?

2. Just because they have my mobile number, can they send me
promotional SMS without taking my permission for it ?

3. They sent 2 to 4 SMS per day for 30+ days as the renewal got
nearer. It drained out a lot of money because I was on international roaming.
I have never authorized them to use my mobile number.
Can I claim damage ?
