Just ring, then keep redialling until they answer. that's what I did this morning. Took me about 3 attempts to get through. And whatever you do, don't let them fob you off with ' can you send an email to webshop@.... and we'll get back to you' because they won't.That'll be the last you hear.

I stuck it out his morning and finally got them to give me a Returns Number.

edit: I did get a reply from Karl Borges yesterday within half an hour of sending my email and he said he'd pass it straight onto the webshop manager- but hadn't heard anything by 11 so I decided to bother them some more. Still haven't heard from David Urch, so it was worth phoning.
