Thank you for getting in touch.
Since the issue you are experiencing is on the creditors’ side we would suggest that you log a complaint with the Credit Ombud, they will be able to do an investigation and hopefully force your creditors to correct their mistakes. Here is a link to the Credit Ombud.
You can also log a dispute with a credit bureau, to oppose the incorrect listings/information on your credit record. Here is a link to TransUnion.
Hope this info helps.
