I understand where you are coming from but I don't agree the way you done it.
Why not just ask to inspect the item, take it and run without signing while you are at it?
And yet I'm not willing to pay their extortionate handling fees, especially when they have already been paid for their services and even more especially with how arbitrary their handing fees are, where they increase or decrease based on the size of the parcel. How does the size of the parcel have anything to do with collecting handling fees due to them paying customs fees?
On top of that, what does the signing process have to do with anything? I ended up NOT signing for them because they wouldn't let me without paying the handing fees, even though I had the parcel in my hands, and then when I checked the tracking a few weeks later, they'd tried to forge my signature.
