issue with de app store

On Saturday I bought an iPhone 5c, the operation that generated me W447305540 order. Hours later I had to cancel. Following this cancellation Apple sent me the confirmation email in which he said he would not receive fees in this regard, however, to check my bank account was debited U.S. $. 587.43 for the phone I bought and later.

Let me know how I can do in this case? How long should I wait for receiving cleared refund in my account?

Grateful for your attention
