Pathetic Service

I had a loan with Izwe loans. I subsequently went under debt review and this fell under the debt review process I was going through via Debtbusters. In February 2020 after almost 5 years I decided to pay up all my accounts under debt review. I contacted Debtbuster and they began the process of getting settlements figures. We received a paid letter from Izwe on the 07 February 2020. And the process continued until all the accounts on debt review was paid up. Due to the lockdown this only happended on the 01 June 2020 when all my paid up letters was provided to me as well as submitted to the credit bureau to update the system. It has been a struggle to get the debt review status removed. Eventually in the middle of July the status was uplifted. However on Experian there is an arrears amount of R7886 that reflects on my account. Both Debtbuster and myself have emailed Izwe Loans and Experian with the paid up letter attached to get this corrected and removed. This has been happening since 29/06/2020. We keep sending the paidup letters for all the bureaus as well as Izwe to get his removed. Izwe loans does not even acknowledge the emails and when trying to contact them the no just rings and cuts out. All I want is for this issue to be resolved. I would greatly appreciate it if someone can communicate further and advise on a way forward.
