daylight *******

I had a clothing account with Jet and decided to pay up the account I asked them to close the account they said since it was a Saturday they wont be able to, a month later I started receiving messages that I was owing and later phone calls that my account has been handed over to Blake and Associates that I was owing about R900 that amount was divided in into two payments. I had to make an online payment of R460 and the other R460 will be debited from my account and I did exactly that , I did not receive any paid up letter or anything instead I started receiving phone calls again that I'm still owing R460 up to date the latest message that was sent to me is that I am owing R633 ..THIS IS DAYLIGHT ******* !
