Invoiced after Closing AND Paying outstanding payment, ON TIME!

I closed my Miladys account, at Fourways mall, in November 2019 and paid the full outstanding amount. The woman ensured they will close my account. Now i receive a statement with interest running in December. I advise that you solve this problem immediately and send me a clearance letter.

Reason for closing account: poor quality! Handbag tore on the inside zip after 1 week from purchase (fourways mall). Boot strap snapped off after 3 weeks of purchase. (fourways mall). Sweater collar ironed right through to the back of the sweater (mall of africa) . Sweater overthrow hole on front.

Poor quality so I close my account. Now you invoice me for December. For WHAT EXACTLY? YOU GAVE ME POOR QUALITY AND NOW YOU PROVE POOR AFTER MARKET SERVICE!
