Utterly frustrated and disappointed with the Service🤮🤮🤮🤮

I bought the sneakers online using my mom’s account, I did not like them, I went to Sneaker Factory Shop in Dr Pixley kaSeme Durban branch to exchange. I asked the salesperson if I could the exchange and she said yes. I took the sneakers I wanted proceeded to the till to do the exchange, Sifiso processed the transaction and Nompilo authorised the transaction. My frustration comes after all this has been done because this is when I was asked if I bought on account or cash. I told Sifiso that I bought it on account and then Nompilo said unfortunately that can’t help me because I need the card to process the transaction, why are they reactive and not pro active I’m utterly disappointed and frustrated because they failed to tell before doing the transaction, worst customer experience that I ever encountered.🤮🤮🤮🤮🤮🤮🤮
