That's awful. I've been on the same series of events, and only a week after had payed them and already getting worried. I've paid with Paypal, so im considering reporting the transaction and ask for a refund.

Any updates? Im waiting for about a week now; Apple asked to verify my identity which I did but still pending

I think each enrolment is associated with a particular ID.. so it's like even if you successfully completed the purchase , let's say via the Developers app, the browser still remembers the previous assigned enrolment ID, and asks to complete the purchase. im almost certain that It will lead to getting double charged...

Any updates?

Any updates? did they got back to you ?
