Don't take it too much to heart, luv!
Have given up expecting any long distance purchase to arrive and be exactly as seller described. Especially when dealing with CL or something else outside of eBay.
As one knows the heartache, best thing to do now is make some lemonade from those lemons. Long as the machine is in working condition with no leaks am sure you'll find a way to deal with the rust issues.
When my Mobile Maid arrived it had two rather large holes in the Plastisol lining, one had eaten right through to the outer tub. Patched things up and the thing has been running ever since. No, it's not picture perfect, but anyone who is that nosey to look inside my dishwasher and comment really isn't someone I'd want to be around anyway. *LOL*
