Rude collection call

What is the name of your state? Tennessee

I don't really know what this falls under so please bear with me. I received a collection letter in the mail yesterday about a debt that I refuse to pay due to services not rendered to me. I get a call from the collection agency today and when I told them I was writing a letter of dispute, they asked me why. When I told them the gentleman asked me why I was disputing the debt, I explained to him why and then he asked me if I had any proof and when I said yes he said that I was a liar, yes liar, and that the judge would even say I was lying. Well, I got a little upset and told him that he was not being very professional about the situation and he told me that I was not being professional not paying my bill. Well, I got mad and screamed at him and he screamed back saying that he was going to take my house and car and told me that I would have nothing. When, I told him that everything was in my husband's name he said he should have guessed being as I don't pay my bills. I was not going to be degrading by this gentlemen so I got mad and said a few choice words and he proceeded to laugh at me and asked me if I kissed my mother with the same mouth that I was talking out of. I have never encountered such a thing and I really don't know what to do. Please help

We need more information. What kind of debt is it? Why are you disputing it?
