This evening I received a phone call from a California phone number that I didn't recognize. I was busy at the time and let it go to voicemail. About 10 minutes later my phone beeped to announce an incoming email.
It turned out to be from a sales rep from a board house wanting to know why I "stopped" ordering from them. The answer is easy: I placed one order with them, and they screwed it up. Then they argued with me about whether they'd screwed it up when all they had to do was compare the Gerbers with the board they delivered. There's an obvious difference when the pads for an SMD are missing, leaving only the stubs of the traces that are supposed to connect to them. Especially when the customer is telling you where to look.
Oh, but they've "invested $45 million" in the last 10 years upgrading their equipment and carry ISO this and ISO that certifications. Their new brochure looks nice, but did they also replace the customer service people? Reputations are easy to tarnish and hard to rebuild, and I have no incentive to give them another try.
(Also, their prices are almost double that of the European board house I've been using, and their product is gorgeous).
