Product ordered on 08/03/2021 by Singeot D.

The site, the order taking and the sending nothing to say, at the top of the top! But the delivery then... it's a disaster! The delivery man came 2 or 3 times to my house without depositing the package (an envelope that fits in a mailbox ...) but instead has put a notice to pass ... why? There was no need for a signature or anything else as it is the 3rd time I order and I receive my piece on time even in my absence. So of course I received the piece late and the work was delayed. This is not the fault of your site but the carrier. On those, happy end of the year, the team and see you next time for new orders!?
