Bad service

I was at Pick n Pay Table Bay Mall on Sunday. My cashier was Busisiwe Dyonase. I asked to draw money at the till and was told I couldn't. The cashier called someone else over and they said I couldn't draw 'cos there was no money. I asked if they were a manager and she said no she was in the cash office. When I asked for a manager I was told one wasn't available. I said this wasn't acceptable and they must call a manager. All I got in response was "eish". Seriously, what does "eish" mean? Is that an acceptable response to customer service?
