Bad customer service

Today at about 15:30 I went to pep stores meadowlands and had a shock of my life, I had bought a dress which was big and wanted a refund, cause already i got something in the other branch so a refund was all I wanted. I was helped by the lady named Olive Mphaphuli, she had the odesity to tell me the dress was worn cause it had what looked like a stain at the back of the dress not in front now im precisely sure I bought the dress as it was cause I never saw anything on the dress, im regular customer at your Pep never have i been treated like that the, supervisor also was in support of this.

I bought back a dress with a receipt of about R600 I still needed my slip and was told to go make a photocopy at the Internet so that i leave my original copy with them, how pathetic??? The receipt it's self states that aslong you have a copy you can exchange anywhere, she tells me I must go back and refund where I bought clothes. Does somehow pep stores offer any customer compensation for petrol? Cause im disturbed by such nonsense that we receive from our local stores. I want my receipt back as im so unhappy with the service and im definitely taking everything I brought in that store. Shame to the sales assistant whose rudely influenced by her superior.
