Urgent: SHEIN Refund Still Outstanding After Two Weeks

I placed an order with Shein on 24 July from Sydney, Australia, which included several dresses, a jacket and a tee. When I tried the items on, the dresses were too long and some were too small in the chest area, the tee was tight in the shoulder area, and the jacket was a bit too big, so I decided to return them. I sent the return back on 15 August and Shein has already confirmed receiving my return, as can be seen from our chat history. Despite this, my refund of 350.58 AUD has still not been processed to my account and I am still waiting for my money to be returned. I request that my refund for this order be processed and paid back to my original payment method as soon as possible and that I be informed in writing when this is completed.
