Pick n pay liqour closing time

Yesterday 25/08/2020 I went to pick n pay liquor at Diepkloof square it was 16:45 and already the door was closed, and at the door they have displayed that they close at 17:00, so I asked the gentleman who was at the door what time do they close he said 17:00, then I said to him its still 16:45 and he said their system close at 17:00 at the door they close early, so I want to know why at the door they display 17:00 closing hours but they close early before the time that they have displayed at the door, can the Pick n pay management at square please fix this.
