Disgusting Service from Woolworths-Ref No:***

Disgusting service from woolies!!!!! I have been one of woolies loyal customers for years, I've also started utilising their woolies dash app a lot as it made my life easier...well so I thought...woolies has been billing me for items out of stock and never automatically refunded me all my funds since as far as January !!!! I had to be the one phoning and requesting a refund, I had to speak to different consultants and spent over 30 minutes on the phone, I spoke to Regan , Kayla Paulsen, Leah from their customer service department, after all the frustration and time spent , I was told I need to phone my bank because on their system the issue is resolved, how is the issue resolved when I still haven't received my refund??????why must I be the one running around to get this corrected and get my hard earned money back??? I then had no choice but to phone the bank of which I was told woolies is supposed to send them a request for collection?? Woolies, what I want to know is.... is this how you treat customers? Is this what your brand stands for??? It's the incompetence for me, why doesn't your system block me from adding an item that out of stock to the cart? Why must I pay for something I do not have????
