bad customer and stinking attitude from senawela till controller at jubilee mall

I went to pick n pay jubilee mall on the 24 th of dec, so I wanted to exchange some dress which I bought last month and it is small and I lost the slip, so wanted to exchange it for a bigger size which was not there, so this till controler or what ever she is, gave me an attitute and told me I must go sell it if it is small, they won't exchange it without a slip, her name is sewela or something like that, she has a gents hair cut, she really made my shopping unpleasant, so I am pleading with headoffice to tell me where can I exchange that dress, or where can I sell if pnp can't exchange you have ro sell things that don't fit you, as you don't even have a fitting room anyway, those retarts are treating our parents bad there, they think they can get away with bad customer service, she doesn't own pnp, and she must treat customers with respect and she must wear her ****** name badge I had to ask around for her stinking name, thank you can I be assisted please.
