i was a merchant in CJ for a short time 2 years ago
and the mailing system sucks for merchants just as much as it does for affiliates - i dont know if theyve improved it since then but back then your cj mailbox was full of messages which had nothing to do with you
as far as see - contacting through CJ just wont work - youll have to contact the site directly - find a contact email and explain the situation - theyll more than likely accept your site
you have to remember the size of the cj network - if they are manually reviewing sites they simply do not have the time to full review every site - they more than likely get a few hundred applicants every day which is obviously tmie consuming
good luck
