3 stars for lack of original invoice 1 more time

Hello,
I bought these puzzles to also benefit from the promotion of Ravensburger reimburse the 2nd cheapest puzzle (which was the 2nd at 1 euro) if given the original invoice after purchase, or as usual, in the packages, NO ORIGINAL BILL !!

The problem would be solved if I could cut the barcodes of boxes gold is a gift: annoying is not it?

I would not write if it was the first time we ordered a pc screen tv which was also 22 inches: delivered without invoice, after request from your services only response is a duplicate which will serve me for nothing in the event of warranty claim! Moreover we just received a 3d blu ray player also guaranteed for 2 years, but delivered without invoice again !!! what does it do to have a systematically invoice in original packages (which are oddly there for small purchases such as books and DVDs) must notify consumers of companies or continue your service to justice ??
you will understand what I expect from you the original of missing invoices and not duplicates in a week (and not three weeks as you set the last time);
after the many purchases on your site all these years, it's still the least thing
thank you
