Did your package already arrive to you or is it still in transport?

You can try using https://corrupt-a-file.net/ and sending it in an email and playing dumb as fuck. This might call for contacting multiple people like you've done already though. Calling angry as hell or emotional about it to the point of hysteria may also work.

You can try PS'g a screenshot and if they say something's wrong on it you can say that you called the customer service of the freight forwarder a shit ton of times (20+) but they've insisted that your tracking matches up perfectly.

When you're feeling remorseful for someone how was it done? Think about it with a clear head and not in panic mode like you are now.

If you really can't lose this money chalk this up as an L, send it back for your refund, and regroup for the next try.

Yeah it has arrived I'm just fighting for a refund so I can make profit.
Thanks for your idea.
