This is still an issue. I bought one license. The confirmation page said 'Your benefits are available immediately'. So I went to my benefits page, because I needed to update my app. It said 'You do not have an active membership'. I have network problems, and websites have problems, so I figured the order didn't go through. I went back through history and submitted the order again. Still nothing. I check a few days later, and the orders aren't pending any more - both have processed through my bank to completion. Apple support would not reverse them when contacted. They asked me to fill out extra paperwork. I have contacted my bank instead.

Well it's been a few days for me. Both charges have ceased to be pending - they have twice the money they should have from me, for a single service on the same account. It's embarrassing that they event allow this without a check against the account ID for the subscription period. I wouldn't even mention this if their support had been helpful. I have contacted my bank instead, and I strongly recommend everyone else experiencing double charges from Apple do the same, as they will both clear.
