Answers.Text: they sent me 43 new tiles now the third times but still no answer and of cause still the same mistake. So for now I ended up with 129 additional bricks which I do not want to use. I am considering to do this 10 times more and open up a specialized BrickLink store.

Answers.Text: Since you now have so many spares, you can try polishing one see how difficult it is to remove the cosmetic flaws. Toothpaste will probably work, but I expect you'll end up with a matte finish. If you have access to very fine abrasives (or very fine wet sanding paper), you could also give them a go.

Comments.Text: Looks like something is wrong with one of their machines and it scratches up the surface. What I do find interesting though is that you keep getting scratched tiles even as replacements. While parts are moulded in several different factories (the ones we get in North America are mostly from Mexico), as far as I know, all replacement parts come from Billund, Denmark. So it's really odd that both the original parts and the replacement parts have the scratches. It seems to indicate that you somehow ended up with parts from the same factory made on the same machine.

Comments.Text: @Stephen. Actually, I was thinking the opposite, contact them again and see how many times they would send the same stuff or if they start to change the strategy, get into the case and send good bricks or react in another way. This are only some bricks with minor problems but sending the same damaged stuff twice means somewhere the internal process is flawed. I have no use for the tiles, sold the model anyway, but just out of curiosity.

Comments.Text: @TheBrickBlogger. Yep, I absolutely agree. I wonder if this also indicates that Lego is becoming  victim of its own success and is starting to lose quality control. There are some videos online where you can see how they supposedly test the bricks in detail when starting a new batch. It is not easy to miss this obvious mistakes.
