Finchoice Account not getting cleared on ITC 9 months later,so stuck

Never been so fustrated in my life,literally stuck with Finchoice Account still registering on Credit Bureau almost a year later after account was paid off with paid up letter sent to me as well

Been trying to secure a home loan after i settled my debts,but finchoice has been sending me from pillar to post but still issue is not yet resolved,got accounts mixed up and everytime i call or log a dispute to get me cleared,i just get told email has been sent and i must 21days but 9 months as still calling and sending emails and getting no assistance at all

have phoned their legal department,accounts department,head office but till today Finchoice still updates account on ITC as in errears

dont know what to do anymore to get this fixed,horrible experience
