Woolworths ripping me off .

I have being paying my account with Woolworths for 5 months with instalments of R500 per month, when I called to check the balance, its just gone up instead of decreasing, lady I spoke to says its cause of the low instalment I am making. This is worrying for me cause I called Woolworths and made these arrangements with them. I don't get how R500 per month isn't making a difference on a R22 000 account, The lady went to further say Ill be paying that R500 forever on this account.
