Consumer protection act

I purchased a shirt Sunday just before closing in Franschoek. returned it the next morning abt 10 , as the stitching on the button holes , which was visible on the shirt was poorly stiched and was coming loose. was told they don't do refunds , nor can they do a credit and they did not have another shirt , same size to swop. They also cant phone out as phones are blocked . So i asked the lady working in the store for a number and phone from my cell phone . The number I was given , also could not do anything as it was not her store (my question , why then were you phoned ) We then became snotty and 'oh well we have had problems with the lines (********') , there is a similar complaint on Hello Peter saying you block staff from phoning out. I was then advised that they have a clear policy about exchanges , when I asked the lady in the store where its was, as i was standing in the store ,and could not see it , she pulled out a notice and turned it around, and there it was, a hidden notice . Anyway, I left the store with no shirt, no credit note , feeling very uncomfortable. Just then somebody approached me advising she buys in Clearwater mall and has had 3 similar incidents.
