You will need to contact Blizzard Support directly… account and purchasing issues cannot be resolved on the forums.
Use this link to start off : https://us.battle.net/support/en/help/contact/1995/ticket and provide all details in your ticket. Live Chat may be available… that could be a speedier option for you.
Best of luck with this !
