Thanks everyone.

Update: I used the chat function on the website to get into contact with them and they responded to that pretty quickly the first time. Unfortunately all they said was that they had my order, and could they help me? When I responded (within 20 minutes) to say I haven't received my email with scanning instructions and I also needed them to amend the address on my order, it took them a week to respond to that and it was only because I got onto their live chat again to follow up.

I finally got my email with scanning link and instructions the other day, but they still haven't confirmed my order address.

They told me they've been emailing me and to check my spam folder, but my email address is on a private domain name, and I don't have a spam folder. Anything that gets sent to me goes to my inbox (suspect emails have spam in front of the subject).

It seems like something is actually happening with my order now, but it's been a frustrating experience so far namely because after paying so much money I've had little to no indication that they have even been doing anything. Just an email to say please be patient, our waiting list is currently X months long, would have appeased me.
