Do not seal your shipment as the courier must inspect the contents.

I assume they're asking you to take It to a DHL Service Point? If so, It will be checked.

No, they will pick it up form the address I declared.

To be honest, you should've researched more Into the carrier and their return policy, as well as selecting a method & Item suited against your (researched) findings.

For example, you could've used the sealed box method, thereby the carrier will only check that the box Is enclosed & sealed, and the same applies to the company- there's no reason to open and check If the Item Is enclosed on (what seems to be) a return In Its original state.

Yes, you're right, That's what happens if you're in hurry, now I know it.

During a SE I have agreed with returning the malfunctioning item to the company

Please elaborate further on this.

I mean: During the exchange of emails to the company I agreed to return to them the defective item.
