Depends how long its been Can take 2 weeks, can take 2 months. If it has been more than 1 month, I would resubmit again.
Its depends on your site. how is your site structure Navigation, content etc. Dmoz have a criteria to submit site in their directory... give me the site URL so may be we can help you. Thankss
Because you didn't read the guidelines? (Which do state they will NOT contact you). The listing time is also shown in the add/submit pages which is roughly 'up to two weeks or more' or something equally vauge. So just move on and submit your sites in directory that do list pages for the end user...
