Damn, China shows it's sleazy side again, that's a horrible reality for that company and embarrassing as mentioned by their company rep!
Sounds like the purchasing department needs to VET their supplier Dealing with china, you need to Check Everything.
Even in my line of work. When we order a product out and it comes in...we verify what we got and inspect the quality. I've been in the business for 40 years and yet some distributors try and slide something by now and again. When I catch something, my first question is why would you waste your money shipping me this and how quick can it be replaced. Some distributors understand that I've been in the business long enough to know what a good job looks like. I remind them that my name is on the final product and I have to deliver it to my customer personally. If it doesn't meet my standards you can bet you'll be redoing it. I spend tens of thousands of dollars with these companies and they have been in the business for as long as I have... quality is JOB 1.
