Doesn't follow what the court rules even after being in front of the judge

Mary Jane took me to court and the judge gave me zero interest and a period of time I did pay off the debt / what the judge required. However once I paid off Mary Jane Elliott still said I owed her several hundred dollars due to interest. How can there be interest when the judge ruled zero-interest. I ended up having to send all my credit reports the Judgment in order to have it removed. Mary Jane's company are brutal do not follow the rules of collections and snub their noses at the law even after being in court
