Disney has no toll-free number for guest use. If they ever did have one, it was many years ago.
The numbers that were posted here and elsewhere on the internet were 'back-office' numbers, for travel agents, business partners like McDonald's, etc. Once they were posted, the call volume skyrocketed, and Disney shut the numbers down.
At this point, even if anyone still has a working toll-free number, they'd be foolish to post it. That would guarantee that the number would soon be disconnected.
