Dody,
The OIA might be of interest to you, as you have made an appeal to your university. There is a cut off time for complaints and appeals to be looked at. It's like an Ombudsman.
You could phone them for advice at this stage, it's free.
The Office of the Independent Adjudicator (OIA) is an independent body set up to review student complaints.
Free to students, the OIA deals with individual complaints against Higher Education Providers in England and Wales.

The other thing I have learned is universities will not take responsibility and refuse many appeals and complaints, so you have to fight your corner. Think of it as a standard part of the process, something you expect to do.
