account paid up but still no paid up letter and credit listing update

I was a loyal Edgars account holder for many years before i lost my job and was unable to make payments to my account. I however became employed again and made sure i settled my Edgars account in full. I made the full payment that was requested on 13 July 2017 and I am still awaiting a copy of the paid up letter i requested should be posted to me. I am also currently trying to apply for credit and my application is being declined because Edgards is yet to update my credit status and even after countless telephone calls and promises to update my credit listing to date nothing has been done. I humbly request Edcon do right by its consumers who have done right by them. The reluctance to update my paid up account status is affecting my daily life. Please post me a copy of the paid up letter and update my credit profile.
