Outdated records

I closed my Woolworths VISA CARD in November 2017. I was give a letter confirming that balance has been settled and account closed, however the reference in the letter does not correspond to my VISA CARD. Woolworths VISA CARD did not update records with credits rating agencies. It appears that I have a monthly installment of R44 323.00. This has resulted in a skewed monthly exposure by R44 323.00 with crediting rating agency. This has resulted in me not being able to buy a property because the records shows that I will not be able to afford the property.

I want Woolworths VISA Card division to send me a letter confirming that the account has been closed. The letter will enable me to continue with the purchase of the property.
