That letter contains your name and address which we don’t need to know and you may want to redact.
But something is missing because it’s telling you that the case against you has been successful and you will now owe money which, if not paid within a month, will lead to a record on your credit file.
This happened between your submitting a defence in April and November. You should have received a N180 from the court, and the case should have been allocated to a court local to you, and all the time you should have received letters from the court.
Do you know if this happened and was ignored, or otherwise?
The letter you have posted says you did not reply to the claim form. If you did, and you can provide some kind of evidence, eg in the form of an acknowledgment of receipt, then the court may be in error.
