Remitly complaint: Holding onto my funds

I transferred fund to my sister in Australia on 18th may 2023 using remitly’s express service. She was in urgent need of fund for her fee which was due on 23rd of may 2023. Remitly first held the funds until 23rd of may I called them time and again to resolve and they kept on saying its commonwealth bank in Aus holding funds and when I escalated it to a manager they started showing the funds as delivered. I called back informing that its not a true story she hasn’t received anything. I do have statements from commonwealth stating funds were never deposited. To which they said we will escalate it will take 3 business days and they have been doing same thing every time I call they say we are going to escalate this and its 1st of June now still they haven’t done anything. And telling me same story we will escalate. Who is responsible for the financial loses me and my sister went through. They are just fraud and scamming people.

I want my money back and I want them to compensate for my time, stress and financial loses I incurred due to their incompetencies
