Question:Q:why have you deducted my account twice for this program
Only, why have you deducted my account twice for this program, where I paid this program before, can I refund this financial cost, then cancel the existence of this program on my phone, thank you very much.
We haven't deducted anything from you, we are fellow users and these are user forums. If you think that you've been charged when you shouldn't have been you should contact iTunes Support e.g. via your purchase history or the emailed receipt.
