Well, this is something new. The HK police replied me with the following:
The director of 'Black Arrow Ltd' is located for enquiry. After
enquiry, he is willing to deliver the product to you but refuse to refund.
If you accept to receive the product, you could contact the company by
email directly or inform to the director to contact you by me.
What total bullshit. Their hardware is completely useless by now (and has been for some time) - even if it doesn't explode and burn your home down.
