Update: After following up the response I received from Apple with:
"Thanks for your reply. I'm sure you understand that what you have said is not legal. You cannot vary the terms of a contract and just keep my money — the law is very clear on this.
I have now placed the transaction into dispute with my card issuer, and they will issue the charge-back to you shortly.
All the best with your toxic practices in the future."
I have now received this in reply:
We are pleased make an exception to our no refund/no exchanges terms of purchase and have processed a refund for your iPhone Developer Program order.
Although we have processed your refund immediately, we request that you please allow 7-10 business days to post the transaction to your cardholder account.
If you have any questions or need further assistance, please let me know.
iPhone Developer Program"
