DishTV — Harassment from DishTv

I have been harassed by DishTv for past so many years and I am fed up of these call. I need help to put a court case against these Dishtv because I never opted in for these calls. As a senior citizen I implore to be helped because this DishTv people call me night and day after telling them thousand of times not to call me. DishTv company should be ashamed of themselves and I wish no one uses DishTv ever again. I am reachable at [protected] for addressal of my issue.
