Are you sure there are 4 charges pending? If there was an error, and if the same reference number (or did you mean telephone number?), the charge may have only gone through once.

Chances are, this will all be resolved pretty easily. I don't blame you for being mad, especially if you're convinced they're trying to take your money. Take a look at things tomorrow, and consider placing a support call - I'm sure they'll work things out to your satisfaction (as long as YOUR expectations are reasonable... )
