Hey Author:
How did they threaten your family? Did they say they eere going to sue you? Did they call youy a liar when they asked you to pay the bil, and you said no?
Be careful, I dont know what kind of collections actions Viking Services can take in your state, but if they can garnish wages, and the debt is large enough, the will probably sue you.
Please respond to this, I would llike to hear the specific threats made to you.
