unhappy disappointed regular customer

Hi..i went to ultra liquors on Sunday 10th November 2024 @12:50pm …since the trading hours is till 13:00 pm. With bad luck the doors was shut in my face by the employees named Luks and Lincoln...they refused to open the door saying they are closed and I'm a regular customer..i wanted to buy for a event i was going to have the afternoon after work..because of that bad experience i had i had to disappoint my family and friends..by canceling...yesterday(Monday) 11November 2024 i went to go look for a manager to lay a complaint...but what i got from that certain manager was bad attitude he didn't even listened to me but rather scold the young man which is one of the employees infront of customers just because he referred me to him..on the otherhand the female manager was busy discussing me with 2 of her colleges by saying loud "she's just a checkers worker" and started laughing making fun of my complaint...im a controller at checkers and know my rights as a customer...
