You'll need to explain the issue in a bit more detail than that if you want assistance from the Community Forum.
What does your My48 account Transactions page say about recent payments/purchases?
Why do you think that this is a mistaken charge and you're due a refund?
Maybe it was a payment for a membership plan or for the one time activation fee for the purchase of your first plan?
If you need to contact 48 support about this then see the links in my signature below.
