This is a common scam, NOT sent from researchanyone.com OR paypal. Your card/paypal account was NEVER charged by researchanyone.com or anyone, you should be able to verify this through paypal or your banking/credit card institution. If you search that receipt number in google, you will see many people have been sent an email with this same receipt number, under the name Nancy Cornell or other commonly used names.
The scammers most likely sent this from an email that LOOKS like it came from paypal, but if you LOOK CLOSELY AT THE SENDER OF THE EMAIL it did not originate from the real paypal (paypal emails will be something like firstname.lastname@example.org, but a common one used by scammers is something like info@paypal.INC.com). The scammers will purposely make it look similar in order to trick you into thinking the email originated from the real paypal. They want you to respond with your personal information so it can be stolen, and used for fraudulent purposes. Please report that email to paypal so they can look into it and hopefully someday catch the ones responsible.
Rest assured that you were never charged/billed in any way(again, this is very easily verified by logging into the real paypal by typing www.paypal.com into your browser or by checking with your credit/banking institution).
