still freezing cold

It's still cold - that's hardly news though, is it? I am in a state of confusion. I am trying to become a member of the Association for Contemporary Jewellery. I downloaded the application form, filled it in, wrote out a cheque and posted it all. More than two weeks ago. I haven't heard one little teeny weeny pip squeak. So I phoned the number listed on their website and got a strange answering machine - you know how most answering machines say something like "You have reached X but we can't come to the phone, please leave a message" or something along those lines? This one says "This is an answering machine". Erm, ok then. As if you'd mistake it for a real person or something. A bit odd. Anyway, so I left a message and for good measure also emailed them at the general enquiry email address listed on their website - which, incidentally, also states "We welcome information FROM YOU". <-- odd caps and bold theirs! So...no response. Hmmmmmm....
Short of going to their office in London, I'm not sure how to proceed.....
