Delivery people working for The Oregonian have been tossing bags full of ads twice a week onto my property, and I really got tired of picking them up and stuffing them into the recycling bag. So I called their subscription services number and politely requested that they halt the deliveries. I did this several times, and was politely assured that deliveries would be halted, but they never were. Some of my neighbors have had the same experience, and just gave up.
And then there's me.
Since polite doesn't seem to work with those folks, I emailed them and made it very clear that if they insisted upon attempting to conduct business on my property and against my wishes, their next communication would be coming from the state Attorney General's offices, and they would also be receiving monthly bills from me for recycling services rendered. My rates begin at $200 per month.
In a surprising move, they quit throwing junk onto my property. They even sent me the names of the people in charge of "subscription services" in our area. Sweet.
