Capfin update my account on bureau

I HAD THE WORST SERVICE EVER AND I WILL NEVER TAKE ANY LOAN WITH CAPFIN NO MATTER HOW STRANDED I AM,,,,I had issues where I updated my banking App and all debi check were removed including Capfin I did call them to reinstate but they failed to and gave me an option to pay via cash which is how I am paying them now and left with one installment but on credit bureau it doesn’t update that I pay them I am really furious with them coz how can I be paying for 6 months and still be behind with the same months.. I need Capfin to rectify this issue as soon as possible please because I need to sort out my finances for a Home Loan now they are ruining my credit score over **** yet I am paying..I was warned about Capfin but gave them benefit of the doubt now they proving me wrong! I really regret it and can’t wait to finish them next month
