Loan settlement

Capitec keeps bugging me about 0.01 that needs to be settled on my personal loan account. EVERY.SINGLE.TIME. I try to pay the cent it says “cannot exceed available amount” stop sending me messages if the issue is not on my side! I am trying to settle this account, but if you’re not letting me. How will I? Seems like a ****, come the end of the month there’s interest and service fee I need to pay for 0.01 that I’ve been trying to settle. Sort yourselves out Capitec!
