Refund

Hi, I have been billed for apps I didn't intend to use, so I asked for and have been given a refund

BUT

It hasn't arrived yet, and when I had realized what happened I also withdrew my bank card from my apple ID payment options (just to be sure it wont happen again).

Now, will I get the refund to my bank account anyway or should I provide another form of payment to get the money back, or should I add this bankcard again?
