I'm hoping that it's the first possibility - they've been on Christmas break. It would seem odd that they would have a spam filter when using their website e-mail address when MANY people could be contacting them in such manner. We've got filters on our business e-mail as well but I still check EVERY one just in case it's a potentially new client that would like to use our services.

I'll give them till early next week and if no responses I'll look elsewhere.
