Account error still not rectified

I paid my woolworths account on the 07th of July using my FNB electronic transfer but put my name on their reference and account number on my reference. Payment went through but never reflected on my account, I made countless calls and emailed proof of payment to WFS, I was promised that my account will be rectified within 48hrs but my statement still doesn't reflect the amount paid. How do I get wollies to rectify my account?
