I dont care attitude

Horrible service at Steers in Tsakane Mall (eastrand) I arrived there at 09:18 whereas their opening hours clearly marked on the door states they open at 09:00...they had closed at the time of my arrival and just told me they havent opened. A few minutes later , another customer arrived and the lady cleaning there said they havent opened and the customer asked why and he was told its because they are still cleaning the stoves and had no idea what time they will open. So angry as the explanation makes no sense at all and the employees don't have customer service s****s or whatsoever.
