Pep store

I went to pep store today to exchange school uniform,due to incorect colour they told me to go back to the store that kept my slip due to the exchange that I made before at the mall of the north I bought them earlie so I can be on a safe side wen the school re opens,I was not informed that the slip was very important for the next time I would like to exchange ,so they kept it,I am at seshego nd dnt hev enaf money to go there am a single parent nd a student at the same time ,I only need to exchange ,I dnt want money I need to exchange so my daughter can go to school in peace.I even felt like pep wants our money with open hands bt they treat us like *****s wen we want to exchange
