I worked there...
Managers of GreenLawn call it an "aggressive marketing politics" ;o)

These idiots prowl our neighbourhood knocking on doors and leaving flyers and now they have begun calling. Got our first call tonight!  Did NOT leave a message. They have now been blocked.They certainly should receive a "C" Rating - none of their so-called lawn experts actually knows the difference between Kentucky Blue Grass or Perennial ryegrass. they are desperately trying to sell people on the "natural" weed removal program - which does not work and leaves nice big yellow patches where they have sprayed the so-called "natural" weed killer product.As a garden professional - I find these people very offensive, as well as being stupid telephone spammers

They are liar.They did not work as promised.

Yep, they call me every 3 months.  3 months ago, I told them not to call me again, they just did today

Dial *67 to block your caller ID, then call the number.
The recording says
"Thank you for calling Green Lawn"
