northern leaseing So called collections manager call me names and threatened me New York, New York

I have had a contract with Northern Leasing when we had to close the buisness due to the poor economy we informed them and they said not their problem we need to pay, we tried to return the machine and they said we still had to pay. When we lost are house to a short sale to avoid bankruptcy they still said they did not care now even when there is no money they call me and tell me that I needed to man up and threaten me, I asked for their HR. phone number and they tell me they do not have that and I would have to Google it. When I ask for his boss he told me that he was the Manager of collections and the only one above him was the president of the company, which we all know is not true. I have tried to g0 to the company who set me up with to see if they had or could find some one to take over the leases only to find out that the owner died and any one I get interested in the machine say no way when they find out its Northern leasing. I have tried to be nice and to work with them but now I just do not care, I am a veteran and don't feel that anyone should have to put up with this, my company has been closed for over a year.
