Very bad service at steers comaro crossings oakdene

I had a bad expirience at steers comaro crossings oakdene. I placed an order waited there until I went to ask if my order was ready and the ladies were standing there talking so loud and laughing while my order was already done by they didn't bother to call the me or call the order number. When I ask them she said I didn't see you sitting there. What is the use of the order number. They didn't even apologise. And it was not the first time this happened
