I HAVE PAID UP THE ACCOUNT BUT MY CREDIT REPORT NO

Good day<br> <br> i am not happy how home Choice handle my account , i have fully paid up their account through Norma & Bissett i emailed them paid up letter into this email address: [Email Removed] but whenever i order again online it says i have the credit amount of R 3999.00 but all of my orders are all rejected and i dont know why? even my report on Credit bereaus has not been updated not even anyone try to contact me and give me feedback . i sent lots of paid up letters but i was promised it will be sorted out by updating their system but none of this happened even Finchoice they told me Home Choice never sent them updated letter that my account is fully paid, i am their customer for long years but not happy on how they handle my account. me as a consumer is it my duty to send a paid up letter to Transunion,experian,Conmpuscan? is not that the credit provider must do that?
