Possible reason is that installation material and small parts are sent separately, hence delivery can take place at different times.
Example: you receive all packages from the shipping company but the installation material is missing. It will be delivered the next day through a parcel service.
In our shipping department like everywhere, here are human beings working who can mix up or forget items.
Please check your delivery receipt or invoice beforehand if the wanted item is listed there.
Possible reason is a mistake of the shipping company which mixed up goods.
Example: Your order is appropriately loaded by the shipping company. But on the way to you the shipment is mistakenly reloaded and shipped to a different destination.
If the packaging is damaged, please immediately make a complaint to the shipping company and in case of doubt refuse the acceptance of the delivery.
Possible reason can be improper handling of the shipment by the shipping company.
Possible reasons can be defect parts, but also operational errors as well as missing experience with the product.
Examples: defective fuse, loose, disconnected or improperly connected cables, loose screws or nuts, etc..
