Hey mate,
Thanks for your reply. I did submit a ticket request and here was the response.

Hey, the order arrived safety and everything is great :) I am a huge fan of your company! I did have one problem in that the mutation RDA did not have any screws for the posts. My mate lent me a couple but are you able to supply me any spares? I'm going to place an order shortly so can I combine them? Cheers! Sam

Thanks for your order.

We regret to say that we do not sell it separately. We will add it to our to-do list.

Sorry for the inconvenience.

My main reason for finding the replacement screws is so I can link it to them for confirmation that they do sell replacements.
I can only assumed something was lost in translation!
