Credit Report not updated

I had a Jet account which I failed to pay with them then it was handed over to Shapiro Shaik Defries and associates, I started paying them as from the end of February this year and this month it's my last instalment, when I checked my ITC profile the debt is written off as a Bad debt with a balance of R3800 where's my balance is R800, I contacted their collectors they gave me contact numbers for Edcon saying they are not responsible for the listing, I tried to email Edcon and contact them on all numbers provided to me to no success.
