Woolworths No Response Experts

I have been paying my Woolworths accounts every month and find myself with a healthy credit. As a pensioner, I hoped to get a refund for the excess monies. This process started before the 22 May 2024 and to date has still not been resolved. Cannot get a response from any address I can find on the internet. I understand my stupidity but surely this simple request should have been dealt with long ago.
