Hughes review: removal of satellite dishes

I have tried to call Hughes net. The party that owned this home previously had several of Hughe's dishes on the house and property, I wish to have that equipment removed, I refuse to hire an independent contractor to perform this task, I feel it is up to Hughes to do so.
I never met the seller and have no clue as to the telephone number associated with the account. You may reach me by email at: [protected]@gmail.com
