Menlyn istore poor service

Menlyn IStore: i arrived friday 14 jun 2019 before 16hoo to replace an iphone 7 battery. Due to the long queue I was informed just after 16hoo that the technician had already left and I have to come back on the 15 june. On the morning of 15 june at 9hoo I was informed the technician is on sick leave. It is poor service and the customer must go back all the time with the hope he will get assistance. With no other branch option in Pretoria to replace batteries Apple has to look into their technical service capabilities.
