Capitec Bank Account Settlement

I had a loan 4 years back and I struggled to pay it off until the account was referred to a company called DMC , they offered me a discount and I paid it off I even have the paid up letter, but now the amount discounted still appears on my banking App, I phoned capitec they told me they can only clear it next year August, I don’t understand why because I don’t owe them anymore. I am so confused right now. It means it’ll still appear as if the account is on arrears while paid off. Nooo guys
