Woolworths don't want to close my account

I've been trying to close my account since March, they told me to go to store 1st before I pay the remaining balance,. I ended up using the account. Now I payed up my accounts both credit card and store card, went to lenesia Woolworths on the 4th, the lady who help me there was kind no probs, then the lady on the phone told me I have extra payed my store account with R800+ something, the credit card owes hundred and something. I requested that they take the R125 if not mistaken from store account since is extra, she even said to me, I also have an option of buying since am in store then after 24hrs they will close the account, or I must send the bank statement for refund on *** I did that immediately and she said she can't see it, she then said I must call after 24hrs to check, I did and not help. I then resend emails but still my accounts are not closed and no refunded. Instead I received an email that says am owing them R500+ on clothing account, R200+ on credit account. How soo I don't know. Now I called today there call takes me back and forth, when I finally tell the lady I was on call with that I didn't get her name call got cut, is over 7days now but still.
