update my account and close it!!!

I paid up my account with capfin and they sent me a paid up letter but now my credit report is showing I'm behind with two months on my capfin account! This is so unfair as it is messing up credit score when it's the very reason I paid up my account was to improve it. I have contacted capfin via telephone regarding this, I was told it would be updated on the 7th when updates are made. Is capfin intentionally try to do this so clients will remain with then cause accounts are no being closed. Why are you doing this to people???
