I subscribed yesterday for the C$2.99 unlimited US and Canada plan, And a tried yesterday to make a phone call, and couldn't because the system said I don't have skype credit, so please don't say I have to have credit for it, since I have signed for the subscription and now have to be charged to in credit, what's going on?
