Enrollment charged 4 times

I am frustrated with the slow response from the support. I kept paying 4 times for my developer account from 31/12 (3 days ago) and my bank card actually got charged €396. It was because when I logged in, I kept seeing the button Purchase now, although I paid previously. I thought the payment did not come through.

Does anyone face the same issue before? What is the best way to reach the support people? Thanks.
