You said "I do not have a automated billing activated." - so if that's the case you're good.
Note: If you have no payment method on file - then auto-billing option is not shown - it can't be activated.
If you are not sure, contact support and someone will look into it.
If you deactivate auto-billing you will not be billed, and your account will expire at the end of the free trial.
You should be all set.
Was this issue ever resolved for you?
I noticed that there is an email icon on their site - at bottom right. You might want to give that a try.
You should address your appeal to the vokipages site proprietors.
There is no connection.
Voki characters are not videos - and therefore cannot be directly uploaded to youtube.
However - if you like you can record your character from the screen, using a screen recording utility & generate a video . There are many utilities (some free) available that allow you to do that.
When you have the video file, upload it to youtube.
Hope this helps,
