Bad Customer Service, Account still listed even after it was paid up.

If I could give this company no stars I would. I am disgusted by their service. I was a loyal client to them and funny enough another customer of theirs warned me to stay away but I thought they were the best. Only now I realize I should've done my research before going in Business with them.

I paid up my account July 2019, settled it but it still appears as active on my credit account. Listed as late account payment. I went to a Kuruman branch to comfirm that my account was paid up March this year and the lady assisting me comfirmed it was paid up and requested a copy of paid up letter.

Doing so I reported that OK rottens my credit profile and I was told it will be updated within 60 days. Today when I check my credit profile it still shows I owe ok. I also contacted OK accounts department via the website but it seems they don't take this matter serious.. Please sort this out, it makes my credit look bad.
