Appalling service by coloured lady named Vivian at Loch Logan Bloemfontein

On date 08 October 2019 I returned an item that i had bought online so I decided to return it at Woolworths Loch Logan Waterfront Bloemfontein. Got assisted by a black lady who did not have a name tag she looked confused and decided to ask for assistance from Vivian. They looked through the package and told me with an appalling, stinky and *****y attitude and tone of voice that they need an invoice otherwise they can't help. I asked them is there no other way of them to check my purchases on their system because all those items are the same price as those on floor but they didn't have sizes so hence I bought online. This ugly Vivian stood there with a gesture indicating that she won't help me. I became decent and went to the car and fetched my phone and opened up my emails to show these unprofessional *****s that there is no invoice sent to me. The black lady only helped me the second time around and I had to tell her a piece of my mind before such was done. Why do you employ *********** people? Why do we beg for service but we pay your staff salary? Remove these stupid people from the front let people with customer service be put in front.
