Looking for tips on raised beds that started to rust and chip after one season outside.

Purchased five Best Choice raise garden beds from Amazon. Installed two outside, and they are chipping and rusting. Contacted customer service and they asked if we placed the beds in a wet area and that returns were not eligible past 60 days. Completely ridiculous, but here we are.

Any tips on how to stop the rust? Is there a special spray I can use that is safe for vegetables? Should I be concerned about the rust?
