Transunion is refusing to update my profile

Hi, I have a problem with how transunion is refusing to update my profile, I have sent numerous emails to them requesting to update my profile to show as paid up I even sent a settlement letter to them, I settled my account in October 2016 and sent them a settlement letter, they never update my profile until April 2017, when I noticed that I again contacted them and now they showing that the account was paid up in April 2017 not October 2016, I have contacted them more than hundred times I even contacted Capitec which is the account I settled in October to talk to them... when I called they said it is now updated to October but it is still showing April, I really don't know what to do with them anymore, are they this outdatded? thanks
