Query: Missing parts out of the box.

These seem like well made crutches, but by the time they arrived I luckily no longer needed them. Unfortunately, I didn't check them over carefully right away. When I tested them today one of the plastic locking bushings was missing, so one crutch rattles loudly when used, and of course, the return window is long closed.I'd love to be able to contact someone about this, but there seem to be zero links to support for the product, and I know that no one sells parts for these crutches on this island. I'm disappointed in Amazon's product support.
