Deceiving trading hours

On the 22nd of June 2023 I went to Barcelos Secunda to get Thumbs up meal l,the time I arrived there was 20:35 and the staff member by the name of Beauty told me that they were closed already. I asked closed how? because the trading hours at the door shows they close at 21:00, she proceeded to say they close at 20:30 so that they can clean and that I should try Debonairs instead. I am not happy with the service we are constantly getting at the Secunda branch. If the restaurant closes at 20:30 then please remove the 21:00 o'clock thing at the door so that you stop deceiving customers.
