Problem X360dock/Boxzii USB Dongle - UK

I recently bought a Boxzii/x360dock and it arrived today but is missing the usb dongle. I contacted the seller but they will only offer a refund.
Does anyone have a dongle they no longer need?
I have done some quick Googling and have found a website based in Canada that sells the proper Boxzii/x360dock and I have also seen that modchipcentral sell a replacement for the X360key/xk3y/etc but Im not sure if it would work with the Boxzii/x360dock. There is also the fact that they are not in the UK.

So yeah, a few questions:
.anyone know if the xk3y usb dongle works with the Boxzii/x360dock?
.anyone got a spare Boxzii/x360dock usb dongle?
.anyone know of where a Boxzii/x360dock usb dongle can be obtained in the UK?
