Thanks for reaching out to the community for support. I'm happy to help you check the details about the additional charge.
You can use our Charge Lookup Tool. Using this tool will provide you the details of what type of charge was debited from your account. All you need to do is fill out the required information and hit the Look up Charge button.
However, you can also contact our customer service team. Customer service has the tools available to review your account in a secure environment and provide details of the charge. I've included the steps to contact support below.
