Sub sub standard customer service and no accountability from Woolworths

I ordered goods on the Woolworths online App on 1 May 2024. The goods were delivered. Up to today, 15 May there is no tax invoice on my App. I went to the Brits Woolworths store and the staff refused to take the returned goods because I do not have a tax invoice. Since then I've send emails to Woolworths customer service 7 times and got rep**** back by Wafiekha Agherdien - Samuels , just to say someone else will attend to that. I phoned the various call centre 8 times and been cut off every time. The order number is ***. This is absolute sub standard and not what I expect from a leading Retailer like Woolworths. I am stuck with goods that I can not return. Can Someone at Woolworths please act out what you stand for as a Retailer.
