Dnata review: Ground staff customer service near Scoot

I was departing to Singapore on 28 December. I had approached the counter staff where it says customer service. The Woman there was so damn rude. Totally ignored me whilst I was infront of her and was engaging in conversations with various staff. The amazing part was that the people who were talking to her 1 by 1 were also ignoring me, instead of attending me. The best part was that they were engaging in private conversations. I said excuse me and she rudely told me to wait. After 5 minutes, she acknowledges me and was rude when I told her my mum needs to eat coz she's diabetic. She was like if you chose to go then your mum can walk all the way to the plane. What kind of person says that? No empathy? If you wish to employ such staff in an international airport, please sack them as they lack empathy and have no proper training to be customer service staff. Just go home and engage in private conversations. Makes travellers look down on Melbourne with such staff. Disappointing and disgusting
