It was coordinated between driver and someone at their office. I'm guessing they needed to clear things up with the merchant or the driver was already being investigated as they were very keen.

Then that's their problem, not yours, hence the driver has no right to "harass" you with repeated phone calls and visiting your home.

Sealed box method is also a no go as drivers are required to take a picture of the device itself before they seal it in a bag and log the seal number.

They'll take a photo of the "box per se", and not void the manufacturer's warranty by breaking the seal and opening It to view Its contents.

As such (and provided the box Is fully covered In cardboard), the sealed box method will suffice.
