Bad service and attitude

Just went to ackermans pta church street to collect my lay bye. Teller (Charmaine) rudely tells me to pay and go upstairs to collect it. I go upstairs and wait in the line same teller comes up and rudely says who said Imust wait in the line that i should be at another line which wasn't even there. She takes my slip and goes to the back. She comes back without it and I'm not attended by anyone. After 30 minutes pass and I ask who is going to help they said she just left my receipt on the counter. Lerato another teller assists after she assisted a client who was there after me why do we have to complain before we are assisted also rudely tells me that she is helping and so why do i even have to question. Then stops responding and throws my plastic at me
