Pep canal walk pathetic service

To whom it may concern

I really dont understand this policy of pep. That being the only reason for my complaint. I see pep has merged with ackermans group. Well pepkor is for both companies this I knew before you could even shop jointly. I recently bought my daughter a few items at pep. Amongst the items were two dresses bcz i had to get home and fit it on as she wasnt with me. The one I planned to return i put away with the slip bt the day I took it back i saw no slip in the bag and the only thing my husband could think of was that perhaps my son took it out cz we couldnt find it and it was in the bag. My son is two he cant exactly tell me where it is and I couldnt find it. I however knew I wont get my money back but I dd plan on taking smething else I needed. I know for a fact..people lose their slips. The tag was on the item and the store could see it was their stock as per label. I worked in retail for 10 years I assure you we assisted people without slips and most importantly I worked for this group too. What ****ed me off is at the canal walk branch I explained to the cashier I dont want cash I jst want to exchange she was so dismissive of me barely looked at me attitude very unfriendly or understanding just told me I need a slip. When I asked her to call the manager she shouted to a back room where the so called manager appeared. When I worked in retail no matter how close u may think ur colleague is u either use the p.a or u go to them u dnt shout like that all because she was irritated with me. The manager said pep sent out a email to all stores and they jst following procedure. Why does ackermans exchange without a slip yet u dont yet u belong to the same group? Why is the staff so rude and unfriendly? I then decided let me refund all the other stuff in my other bag I bought and spend my money at pnp clothing rather because I am nt asking my money back I jst want to exchange. I already wasted my time having to go home because ur system doesnt allow a manual entry to make a laybye. When I went back the second time I got this pathetic service. Your canal walk is a new branch this is not how u treat customers because the store has great kids clothing. That cashier was very rude and the overrider also tried to be smart with me when I asked her my slip back of the items I refunded. They are making their own policy. I am well aware u can make a copy like I said I worked retail for several years. If u can see its ur stock with a tag on why couldnt you just exchange it? Where is the consumer act ? I am very upset about this and want feedback.
