I'm always getting emails claiming they're waiting for me to execute the order I supposedly made. I just move it to "Spam" folder and delete. Same for phone calls coming in on either my landline or cellphone. If I don't recognize them I don't answer. If they really want me to call them back, they'll leave a message, otherwise I put them into my "block" mode so they have to use yet another phone number to call me with their speel.
