When my RS armour came I emailed them for an update literally about ten minutes before it arrived at my door, I'd never received any communication about it coming, it just turned up.
I'm currently two months into waiting for a replacement neck seal from them and communication has been terrible, I'm still waiting for a response for my last email I sent over a week ago. Guess they're busy again but it is frustrating. I'd just try ringing them, might be the quickest way to get a reply.
