澳大利亚采购需求：黑白超声波、彩色多普勒超声波、心电图、数字X光、病人监护仪

I am writing to express my frustration regarding a refund that has not yet been processed. I returned a veterinary ultrasound machine several months ago, but have yet to receive the reimbursement. This situation is becoming increasingly concerning, as it feels like I am being ignored. I expected a more prompt resolution, and the delay seems unjust. It's important for me to know what steps are being taken to address this issue. I believe that timely communication is crucial in resolving such matters. Please provide me with an update on the status of my refund, as it seems unacceptable that such a significant amount of time has passed without any feedback. Thank you for your attention to this pressing issue.
