I'm as puzzled as you. I've bought a lot of times in
www.subprof.com, and I've never had problems. In case of delay, they always e-mail or call me to explain what's happening, but my orders arrive usually quite soon. You may insist on e-mailing them, or you could also phone. Their phone number is on their website, and I'm sure that they will give you a good explanation. It's possible that the dealer has ran out of stock, or haven't worked during Christmas. In Spain, Christmas holidays are longer than in other countries.
