Unfair listing by DMC

This is the second I write a review for DMC I have two account that were handed over to them the one is for payjustnow which I have already paid with Nimble but it's still showing on my profile with the full balance I spoke to DMC and they promised to have it removed it 7 days and to date nothing has been done, the truworths account is also paid in full but nothing has been done I spoke to a lady/gentlemen by the name Ayabonga where she sent me a message informing me that i she cannot assist because PayJustNow has been withdrawn from their company I'm being sent from Pilar to post and in the meantime I'm suffering because both accounts are listed as adverse of my profile which has a negative impact of my credit score
