Appealing a Small Claims judgement. I need help in finding

Appealing a Small Claims judgement. I need help in finding out how to fix an application to appeal a small claims judgement. I submitted an application to appeal a small claims judgement and the grounds for appeal which was based on significant errors in fact by the trial judge. However, the reason given for the decline is that "an appeal is not a retrial or a rehearing. Findings of fact are for the trial judge."This reason for refusal doesn't make sense to me because it is obvious that the trial judge made errors and did not consider the evidence and my understanding is that findings of fact are a valid reason for appeal.. What I was granted was an oral hearing to renew my application: "The Appellant is entitled to an oral hearing if within 7 days of receiving this order the Appellant informs the Court that the Appellant would wish to renew the application for permission to appeal"Questions:
1) How do I write to the Court to say that Yes I want that oral hearing - I believe I need to submit an N244 application.
2) I also need more time to get legal advice to re-draft the grounds for appeal so that the Court will understand and it won't be declined. How do I ask for that considering that I only have a few days to confirm that I want an oral hearing.
3) Why did the court deny my application based on errors in fact, if it is obvious that errors were made and that is a valid grounds.Thanks
