Check your slips

Bought a bunch of things at senqu Dullstroom the one day. When we got back to the accommodation we noticed they added an extra shirt for R250 that we definitely did not buy. Went back the next day and they treated me absolutely horribly as if I was a ********. They eventually hesitantly refunded me but the way I was treated was unacceptable. It seems they are adding things to bills and expecting people not to notice.
