ARREARS ON MY ACCOUNT BUT I PAID A SETTLEMENT AMOUNT

I RECEIVED A SETTLEMENT QUOTE ON 30/01/2026, WHIH I PAID. MY ACOUNT WAS IN ARREARS OF R160, I DO NOT UNDERSTAND WHY BECAUSE I PAID THE SETTLEMENT QUOTE. I HAVE BEEN CALLING THE CALL CENTRE WHERE I AM HOLDING FOR 15 MINUTES. I PAID THE R160, I HOPE THIS WILL NOT AFFECT MY CREDIT SCORE BECAUSE I HAVE DONE MY DUE DELLIGENCE, ANGRY IS AN UNDERSTATEMENT. WHAT IS THE POINT OF OFFERING SETTLEMENTS BUT ACCOUNTS WILL BE IN ARREAS EVEN THOUGH ONE HAS PAID AS PER SETTLEMENT QUOTE Ts&Cs
