Customer center error message after changing TV package

I called customer service this morning to change my TV package. Now, on my TV I can see that the channels have been changed. But when I go to the customer center on Videotron's website and check my current TV service, it still shows my old package. When I click on "Change your channels" it says: "ERROR   A request has already been recorded in your account. To make any additional changes, please contact Customer Service". Is this just temporary because the website hasn't been updated, or has there been some kind of problem changing to a different package?
