Earlier shop close

I went to the Exact shop in Church Street Mall in Pietermaritzburg, before I went to the store I checked the closing time and I rushed to the shop when I got there ot was 15:46, and I shop was already closed. I stood by the door and a gentleman who was sweeping came to me and told me they were already closed and I was like how come, I checked before I left my house the closing time, and the time on their window says they close at 16:00. He said they close at 15:45, and I told him that when they open they open at 9:00 just as the times on the window says not at 8:45 and he said to me but they have to be at the shop by 8:45 and he added that doesn't matter anyways since they have cashed up already and I was like it doesn't take two minutes to cash up, so I asked for the manager and he said the manager has left, and I asked for the supervisor and he said the supervisor is not in as well and I asked for his name and he said his name is Exact, and I was like how and he told me I want to dirty his name. He even suggested that I should go to the Exact at the Liberty Mall, and I was like I came to this one because it's close and I don't need to hire a cab, and he was like I should be early next time and I was like I was working, they need to be truthful about their closing times... I think the store needs to make their closing time clear, and the employees as well should know times when they should close the door. The guy who I was speaking to had a beard and two silver teeth. He looked like the manager because he was checking people's bags as they left the shop. I think that is why he **** that there is no manager at the shop.
