It can be very concerning to see charges in your account that you have not made or authorized.
It’s possible that they are valid charges and relate to purchases which you may have overlooked, so it’s important to first check your order history to see if the charges match the items you’ve bought.
To put your mind at rest, here are some steps you can take.
Check your purchase history first
You should have received the receipt via email, or you can easily find the purchase in your transaction history. Here's a link to show you how: Amazon's Customer Account Support.
If the purchase is still not recognized, report it to Amazon
In the event that you’ve been charged wrongly, please reach out to Amazon so they can arrange a refund for you as we do not have access to their Payment Systems. Please use the Contact Us option on your device to get in touch with the Amazon Support Staff, or you can also follow this link: Amazon Customer Support
