RE: Question on customer service expectations
I think a bill is in order. (as long as it was reasonable) I'm sure it took a little force to break the PCB, and you didn't have to attempt the repair. Supplying you with a part... that YOU requested, doesn't put damage liability back on the manufacture.
I'm not trying to be harsh... just saying.
So... the way it should be resolved is to suck it up, and accept that you broke it.
