How would the Small Claims Court judge this case?

I was approached by a translation company and they asked me to do a translation for them. We agreed on a price and I met their deadline. A cpl of days later, they said they would not pay me as their revisor thought the translation was not up to their standards. They sent me the revision back and I took the time to agree and disagree with everything they changed. Many things were just rephrased and did not show anything wrong with my translation, it was just another way of saying it. It is not a lot what i want to sue them for but it is more a matter of principles. I approached them and suggested we cut the fee in the middle so it was fair for both parties but they refused to do so. Obs: I have a MA in Translating & Interpreting with the languages involved as majors and can provide the Court with good references as well.
