Caution when dealing with member awsig

I'm currently working with a well known manufacturer of car reproduction parts.
The first part they sent did not fit.
I took pictures for them and returned the ill fitting part with a sample of the part that did fit for them to get the second one reproduced part "right".
The second one is still wrong.
I've now "eaten" original shipping of 20 dollars and the return shipping of 8 dollars once.
I looks like I will have to eat return shipping twice on the second part sent that was wrong.
But to get a reproduced part that fits, I consider the gamble part of the game.
