i subscribed to Adobe Acrobat Pro free trial but i got charged full amount instantly !!

Abdul, sorry for any confusion. Acrobat is a trial with payment, and a refund is available within an allotted time. Please see https://adobe.ly/44Nhkia for complete details. I can confirm that you successfully canceled your plan for Acrobat. Any refunds issued will take seven to 14 business days, depending on the financial institutions involved. ^JW
