New campaigns can take up to 72 hours (3 business days) to review.
If you submitted it Saturday, the clock starts as of Monday morning, so you will have to wait until the EOD Wednesday or first thing Thursday to contact support.
If you make any changes to the ads or keywords, that restarts the clock
Just sit and wait until then, then start to email them through the online support. They cut back significantly on who they will allow for phone support and I have friends that are telling me they can not call in anymore and directed to online support.
