how to find support

how can i contact support immediately if i am having a problem submitting something in an ongoing contest?
i cant find any support on the website and the forum needs my question moderated first before i can be aided.
i need support because my submitted code is correct but it always gives me 0% in accuracy.
i tested my code numerous times and there is nothing wrong with it.
i used the example input and everything worked fine, but when i submit it always says it is wrong.
