Tell us the correct closing time!!!

I stay in Meyerspark and did my Shopping at Pick n pay Silverwater and got a great experience all round. I was missing a few thing so I decided to rush to pick up something at The Grove mall having checked online and it said it closes 7pm.I arrived at Pick n Pay clothing The Grove mall in Pretoria East at 17:50 and doors where already closed. Employees were standing around and just ignored me. Finally one lady came to the door to open for a Customer who was leaving and She told me that the store closed at 6pm and I brought to Her attention that it was not 6pm yet and as at that time it was 17:56 and I asked Her if I could just quickly pick something but She literally banged the door in my face. Very disturbing to see such attitude when people are losing jobs left, right and centre. Very disappointed Client
