Poor customer service - Consumer Complaint for PEP STORES

This afternoon I went to Pep at Queen's corner,around 17:00, I found the door closed, and checked the trading hours on my phone, I saw the closing time is 18:00, waited outside for more than 15minutes, cashiers were busy talking amongst each other pretending as if they don't see Me standing outside, I waited for the customer that was inside to go out, cashier came and opened the door for the customer, she then closed it infront of me, as if she doesn't see me, I knocked on the door feeling like stupid, I asked her as to why is she closing the door without advising me of their rules and work schedule, because I am a customer ,I know nothing about your rules during this time, and for me waiting outside , I was thinking they only allowing certain number of customer inside the store, but guess what? I felt like a stupid, cashier banging the door in front of me without even greeting me or saying a word, pretending as if she doesn't see me, I want you to take your staff back to service training, because isn't only this Pep that is giving out poor services, all your Pep stores cashiers are very rude, they don't even greet customers...I do my shopping here at Queen's corner since is closer to home, but always when I come to the store I get poor service and have to leave the store with a broken heart, always, I need you to take part in this, address it with your staff, and I need feedback on this matter, I hate doing my shopping with a broken heart...Cashier's name is Boitshoko...your staff doesn't know the high five, are you just hiring people without taking them to training ? I need feedback on this matter!!!!!
