Rubbish
Response from developer
Hi, thanks for your review - The shortest duration subscription available within the app is a monthly subscription which will renew every month until cancelled. Once you have taken out a subscription within the app, it should not be possible to purchase another or be charged for another, so it would be very strange if you have been charged twice within two weeks, unless you have chosen to upgrade to a longer duration subscription. As payments within the app are taken directly by Apple, if you can please contact their customer support team, they will be able to arrange a refund for you if multiple payments have been taken incorrectly.
