Paid My Account Yet not updated after a Year

I was unable to pay my account as Truworths gave my account number to a person in Mozambique. After countless times at different stores trying to make payment it was eventually found that i needed a new account number. <br> <br> After making the payment, I was able to close the account immediatly via telephone in the store. A year later the account is still reflecting in arrears which is a bad reflection on my credit rating! How was it possible to take my money and close the account no hassles, yet not remove the amount off my name. <br> <br> I would like this issue to be resolved. I have had no success dealing with the head office and call centre which are useless and do not do follow ups. As it is a year later with no joy. Seriously worst the worst experience as the company claims to give customer satisfaction as their values. Really?
