In my experience any submission in ISC especially in the nature of information update or article takes time for review and it could be anything from 10 to 20 days. Depending on the volume of submissions and contribution by the members sometimes this time period could be less or more but it is a general idea that I am giving for the reference. So, sometimes we have to be patient and if this limit is crossed then we can give a request post as you have given here. Anyway, editors will be responding to you in a better way soon.
