I was so positively surprised by OSH Parks support that I felt that I had to write this thread.

I have ordered several PCBs through them before, without any problems whatsoever. But this time I ordered a board with a very irregular board-outline (see attached images), and the final boards was cut/routed-out incorrectly so that the edges had been cropped slightly.
I contacted the support and asked if this was an error on my part or if it was the PCB fab. To my positive surprise they admitted their error directly and refunding me the whole amount while at the same time producing new PCBs and shipping then free of charge via priority mail!

This is probably the first time in my life that I have ever gotten a refund and a new product at the same time!

The reply I got:
...Oh, shoot. Sorry about the trouble there. Our system didn't handle the outlines on the edge quite right, so it got panelized closer than it should have to other boards. Not a common issue, and usually we catch and correct them.
Definitely an error on our side though...
...Refund's been put through for you. I've also just reran the new set, and marked them to ship Priority mail.
