Worst experience of my life and I'm a Marine!!! Go...

Worst experience of my life and I'm a Marine!!! Got roped by another JYVER to do the Skills demo, but it was actually her JYVE. 10hrs of work I got zero pay!
Went to my seconnd JYVE and it was a double stack. One pallet had been placed on top of the other with no plastic wrap. I was using a ladder to get things off the top.
Job said 235 cases, I had an emergency and had to leave 17 boxes and the teas. To which I was then informed after 10hrs of work I would get 1/2 the pay because the next JYVER said there was 95 items still there?
Dock manager even mentioned it waasnt wrapped safely and JYVE has been double stacking unlike the other vendors.
NEVER AGAIN! I'D RATHER DIE FOR FREE MY COUNTRY than a heart attack for $60.
It's been 2 weeks and I'm yet to be paid for my 1st JYVE.
This isn't even minimum wage!!!
