WORST SERVICE AT MAKRO GONUBIE EAST LONDON

I've been standing here for almost an hour,....I Saw a Samsung Sound Bar online that cost 1700 when I got to your store in Gonubie it was R2000 ...I then ordered it online for pick up which I was not advised that I would have to wait for it to appear on your system. I was shocked after payment that it would take longer than I expected....I am standing here asking for my refund they are telling me it would take seven days... I am ****ed because I don't even live in east London
