Lack of respect towards customers

I was insulted and sworn at on the 31 August 2019 at 21:15 by Interpark staff at Menlyn. I went to the office to report that the machine gave me a half R10 as change. When I got there a young man with a nasty attitude told me I didn’t pay my ticket I don’t have money. When I asked himself to view the CCTV he told me there is no cameras with bad attitude
