Bad Customer Services

I just had a bad experience at Woolworths tygervalley. And it almost feels like a humiliation ritual. I was returning an online order. I had both my delivery note and invoice with me. Then supervisor comes to authorize but then another lady comes, she makes a phone call not knowing it's about me. After she was done, she says no they had to confirm it was me. Now what's the point of the 2 documents? When she made the phone call to customer services she didn't say to them she has the documents. She just told them she wants to confirm the order. So when I got home. I phoned Woolworths customer services and they confirmed what I know. If you don't have those documents that's the time they phone customer serive. What makes it worse is i was with my colleague (a white lady) who was also returning an online. They never made a phone call for her. I was returning at Country Road and she was returning at Witchery. Question now is it about color? Cause what the hell
