I am so upset with their intrusion I sent them this letter:

Dear National Enterprise Systems (NES),

Seeing that you have so much time in your hands you don't know what to do with it, I know some people in regions of the world where farming is done manually. I can suggest (at a reasonable fee, of course) farmers that will be happy to use your service on their farms.

The next time you contact me over this scam, I will proceed with litigation options. How did you even get my email???!!!!

You've been warned.

An upset debt-free responsible citizen.

NB: The 1 star is actually -10!
