Terrible customer service

I would honestly rate them zero stars if I could. I am so disappointed in the service I have received from Cotton On in the last few weeks. I always support Cotton On as I love the clothing they produce and I understand that these are stressful times but I have been trying to get hold of them via email and live chat for 2 weeks and have not received a single email back. I was supposed to receive a refund for clothing that I paid for which they no longer have stock of. I have emailed multiple times and have not heard back from anyone. I have joined multiple live chats and have only ever got through to one of their agents once. I was so relieved only for him/her to join the chat, not answer a single one of my questions and then abruptly leave the chat when I asked about my refund. Cottonon has disappointed me to the point where I will not be supporting them again. Their service is appalling.
