Disgusting service

Went to Ackermans shop 13 c*****dene centre cnr c*****dene&putfontein Rd Benoni what a disturbing service. I’ve never ever been at the store were workers of the store would be screaming literally screaming in the store while customers are in the store shopping. Two ladies Sumekani Lihle who are working there screamed out of their lungs only God knows what for it was disturbing cause I thought something was wrong and almost ran out of the store. Sumekani screamed from the stock from to the door where I was standing at that time. When she got to Lihle who was at the door they started laughing very loud for whatever reason. Customers complained but no one said anything. It is very unprofessional and it is a disgusting behaviour. I can only imagine customers that shop there all the time go through. No respect for customers at all.
