False info and credit listings WONGA LOANS//NIMBLE GROUP

I keep on receiving calls from Nimble Group stating i have 2x overdue accounts with Wonga and this has now been added as negative listing on my credit profile. Since end 2022 i have been trying to resolve this, Wonga keep telling me its a mistake and they have instructed Nimble to remove it and Nimble Group keep telling me they will request from Wonga if they need to remove it but the listings remain on my name. Not sure if anybody realises that you cannot have two accounts with Wonga... you need to settle the one before you can get another one... strange how i have a current one with Wonga but "apparently" i owe on 2x other Wonga accounts. Please get your communication in order as i email Wonga and Nimble Group on numerous occasions and still this inaccurate listing remains against my name.
