One thing that I can't seem to understand with the boxing method is that if you send nothing in the box, will the company get back to me? Because usually refunds get processed when the defective item arrives, don't they?

Please explain a bit for me. Thanks to you and OP for this method, will report back if I'm successful.

They will most likely contact you and state that the box you've sent was empty and that they only process the claim further if you sent the item. Just say that you've sent the item and wait for their response.
