RMA processing

Return of unopened/unused goods (wrong delivery, wrong order, etc.)

Handling of Transport damage

Quick help in case of transport damage and missing quantities in the package.

Please note:
→ Leave the goods and the shipping box unchanged in any case.
→ Do not use the goods under any circumstances.
→ Report the damage immediately, i.e. within 24 hours.

The shipping box must be kept until complete clarification!

Obviously damaged/re-taped packaging must be noted on the delivery papers when the consignment is accepted and countersigned by the driver.

If the driver refuses to note the damage, it is best to refuse acceptance.

If one or more items are missing or wrong in the package, please contact us by e-mail at : revision@siewert-kau.de

Advantages of a direct processing through the manufacturer:

  • shorter processing time
  • prompt repair/replacement
  • direct and faster communication with the manufacturer

For the following product groups, direct processing via the manufacturer is required

  • Brother consumables (ink, toner, etc.)
  • software
  • Gaming chairs (Akracing / DX-Racer etc.)

**** Important information regarding Brother Ink Cartridges ****

We would like to inform you that there may currently be longer delays on the transport routes. As a result, the ink cartridges from our warehouse have a minimum shelf life of at least 3 months instead of the recommended minimum shelf life of 12 months. We would therefore kindly ask you to refrain from returning these ink cartridges.
