@Alld, Did you try leaving the date field empty?? Sometimes I've found use of the date field a little confusing (I'm sure others are ok with using this feature, but to me, it's just one more filter and one more thing that could go wrong).
It sounds like your PD is 10th Jan. I would enter "A-1401" in the case number field, select the case type as PERM and leave the "from and to date" fields empty. Everything else should be empty or no other selection needs to be made. If you see your case number in the results, great. If you dont, they still haven't processed your application yet. Keep searching this everyday. Good luck!
