How do I get my refund payment from Apple?

Re: How do get my refund payment

For Apple products and purchases: First you request a refund:

See how to: Request a refund for apps or content that you bought from Apple - Apple Support

and

if Apple approves it, the refund will go to the same payment method that you used for the purchase.

For how long the refund takes:

See how to: Check the status of a refund for apps or content that you bought from Apple - Apple Support

If Apple refuses the refund:

For products that are not produced by Apple: your money may have gone to a third-party vendor or developer:

The best source of help for a product not made by Apple (a third-party product) is the company or person who made it—its vendor or developer:

Contact a third-party vendor - Apple Support

or 

Apple Support have an article online that may help:
