PAID UP ACCOUNT STILL NOT UPDATED

My husband asked me to do a review against Wonga He had a loan with them and do to unforeseen circumstances he could not pay his account was then handed over to the Nimble Group. on his credit profile both Nimble and Wonga had listings on for the same account same amount everything. We settled the loan with Nimble Group in March of this year and they removed the account from his Experian profile to date after many many emails and calls to Wonga they have still not removed the listing till this day this is causing prejudice and ruining our lives
