Easton Berry Collection *****ulent

My account was handed over to Easton Berry Collection by Truworths due to none payments, my balance was said to be R5000. I started making payments on the account. I then called beginning of 2024 to check what my balance was and i was told it was R3000. I asked the agent i was speaking to why it was still so high when i have been making regular payments, she said its because i was not paying the required amount so the account is incurring interest. i therefore with the help of the agent decided to increase my monthly instalments. I called again to check after 4 months only to find out it is still sitting at R3000. I had to make the agent do the calculations for all the payments I have made, and with that we got that the balance should be R1700 at this point. However because of interests, sms, etc it went up to R3000. How ridiculous is that. What interest are they charging that in two months the interest is R600. These people are ****mers. How am i suppose to finish paying for this account if they keep charging riduculous interest. I'm livid, i even asked for closing discount and the agent forced me to acknowledge that R3000 is my current balance and told me it will be 20% of the principal, i mean who does that. When i asked another bank for a closing discount on my credit card they gave me 70% off. This is day light *****ulent.
