clueless.
1. Find out your ICB credit rating. Go to Irish Credit Bureau site and apply for you Credit Rating.Costs e6.
2. If it shows the last 24 mths as up to date ,not only have you no issue ,it is a good ongoing credit ref.
3. If it shows slow payments contact Ulster and ask them to amend their records.
4. If Ulster do not ,you can still ask ICB to note your concerns.
5. If you should be looking for credit in the next 5 odd years ,keep copies of all correspondence + your reasons for appearing (bad)
Hope this helps.
