Great info, kernowlass! Thanks for helping out. 
In addition to what kernowlass has said, if you did not authorize the charge and you don't see it in your PayPal history, you'll want to dispute the transaction with your bank or card company. They'll replace the account number to ensure you don't have any more unrecognized charges, and they can let you know what options they have to look into it. I hope this helps!
