<p>My account was handed over and i paid it in full on the 6th of August 2015 i then called edgars over and over for a paid up letter eventually received it and was told that credit bureau will be updated accordingly until now it has not been updated when i called transunion was told that edgars did not update anything on my name since 2014 when i called them the cosultant told me that they updated it on the 20th of November 2015 but wherever i go this account is picked up and it reflects as owed, their consultant couldnt explain that sad part is i was buying a house i couldnt even get it because of this account reduced my scoring on credit bureau and when i went to them no one was willing to assist me at their stores or call centre i am stuck with a negative account that was paid up over a year ago .
