Billing charged when no subscription

Also has it occurred to you that someone, a house/family member or So Called Friend, has taken your CC number and used it to sign up for a subscription using a different email address, IE Adobe ID?

There are no free plans — only a 7-day free trial. It's possible that your plan used one email address and you used a different one when you called. That would explain why they can't find your subscription. There could be other reasons, but only Adobe support can sort this out. This is a user forum and we cannot see your account information. As John says, contact Adobe Customer Care: https://helpx.adobe.com/contact.html
Click the chat icon in the lower right and type "agent" to make sure you are talking to a human and not a bot.
