Do you have an iPhone and happen to be using iMessage?
When sending texts are they both being sent by the same number or different ones? I believe that when you port you are given a temporary number until it has been successfully ported out. Chances are you wont be able to send texts from the old phone come tomorrow.
It's the weekend and it takes longer in general then. Monday should be fine. If nothing still you can always send a private message to Koodo via Facebook or DM via Twitter asking about the status but its one of those things that get done when they get done.
