Theft daylight

I have a shock of my life yesterday at Woolworths JHB kerk str went to do exchange of one item which I bought the previous day on the 25/03 got to the till point and the lady went to the ppc they spoke she came back continued with the exchange without telling me about the reduction I even had to ask for my slip as she didn't intend to give it to me, I noticed the difference on my way out went back and ask why different amounts she just told me I came there to exchange not to refund I got confused and asked for the explanation the left me standing there and spoke on the phone I then went upstairs asked another lady for help she told me she was supposed to refund me and sell the other item to me, we both went downstairs to the customer service lady (Bridgette) she said to the lady I told this guy wat does he want now? I felt so disappointed at her service she didn't even wanna help and didn't care about wat her colleague was trying to help. My question is is woolies now hiring people who randomly ***** from customers is the company that desperate to keep such incompetence and dishonest people? Why would I trust them with my money again or it's not good enough anymore why other woolies stores explain the refund was supposed to be done first(Carlton store) this people have no respect for customers at all or are they using our money as transportation money or for lunch why can't they be paid early? I need investigation to be done on this girls I think they believe that woolies is a ****a shop where they can rob customers. CT Modisakeng ********** 713 cashier Elizabeth customer service Bridgette
