Dish Network Harassment

I have been getting telemarketing calls from Dish Network at least once a day and often 4-5 times a day. The calls are sometimes as early as 6:00 am and as late as 1:00AM

The callers are always Indian or Pakistani and they are rude and abusive.

I am registered with the Do Not Call registry and I have spoken to Dish Networks' own internal department that claims they are aware of the problem and can help. However, nothing has been done about it. This is the worst company ever and I really want to sue them or do something to attack them where it hurts for violating my privacy repeatedly. I can't believe we are so helpless to these pigs and that we have no recourse to their harassing tactics.
