Bad & unprofessional service

I bought a wrong charger and did not even open it. 2 minutes later my partner tells me that it's not the correct charger. I immediately went in to exchange but they did not have the one I wanted so I asked for a refund so that I can buy somewhere else because I want to charge the phone now and Shaun the Store manager in Sandton City refused to refund me and yet she still kept the one I bought. I really bagged her and tried to make her understand how important this was but she treats us like we are nothing, like we are fools telling us that they do not do refunds but there is nowhere written that they do not refund. I truly believe there is something wrong in her head and the management position is too big for her. I need my R300 back as soon as possible. That is poor customer service and relations. Shaun needs to go back to school. If no action is given or done against her, she will run the store down and one day clients will lose patience and bit her up. Shaun is rude and not professional at all.

I did not want to be rude because I did not want to disturb operations and other clients
