Ring-ring.
Me: "Hello?"
Scammer: "I'm John."
Me: "What do you want, John? I don't know you."
John: "If you remember, last December you filled out a form for a free vacation." (I had to ask him to repeat this as I could not understand him."
Me (loudly and forcefully): "NO! I DID NOT FILL OUT ANY SUCH FORM! NEVER, NADA. WHY ARE YOU ANNOYING ME?!!"
John hung up on me. Go figure.
