Bad attitude from PEPstore bloed mall pretoria manager.

I bought a school trouser at PEP store but it was not fitting well I returned it and asked to try another size since the issue is the waist of the trouser ,so the other new size for the school grey was still small I asked if I get the one with elastic they don't have ,I must take 32 I said it will be too big I will prefer refund and check other stores ,they called the manager Gloria she gave me a hell of attitude infront of customers accusing me of changing a trouser at 16:45 of today 2025_07_24 shouting am telling her to check her slip it was yesterday slip,she talks with attitude making it as if I have done something wrong infront of customers they way she was angry they gave R30 change instead of correct amount I had to tell them guys that not the whole amount refund .my problem is that why is she having attitude making others as if they did something wrong while she is the one who failed to read information in her slip.Gloria needs to be nice towards customers
