Thank you for posting, @svetlana24342857h722.
My apologies for any confusion, but the two charges are for your Adobe Acrobat Pro and Photography plan subscriptions. This is why you are being charged twice a month.
I see that you have been using both services regularly, but if you no longer need either subscription, please see https://helpx.adobe.com/account/individual/subscriptions-and-plans/renewals-and-cancellations/cancel-adobe-subscription.html for information on how to cancel any unneeded subscriptions to reduce the number of charges, @svetlana24342857h722.
Please see https://helpx.adobe.com/account/individual/terms-policies-and-regulations/adobe-subscription-terms.html for information about the cancellation and refund process.
Please update this public discussion thread if you have any additional questions, @svetlana24342857h722.
