BP Rivonia Wrong price for 93 fuel

I have filled fuel at BP Rivonia service station numerous times I want to query why I am been charged for 95 unleaded fuel. I asked the the petrol attendant to fill 93 unleaded . He is using the 93 pump yet when I get billed, my slip shows 95 unleaded at the 95 unleaded fuel price? Why is this?
