The company is Natural Way Lawn & Tree Care located on Brown Rd. in Lake Orion, MI. Their main number is 248-239-4000 but they have a string of other numbers like 4014, 4015, etc. Obviously they need them for illegal telemarketing calls.
Principals are Keith Fetzner, Owner; Patty Berriman, Office Manager. The toll free number is 888-224-7336. Give them a call and run up their toll free bill. Or send them a "love fax" at 248-239-4020.
You can Google them and find they had 22 BBB complaints recently (http://www.bbb.org/eastern-michigan/business-reviews/lawn-maintenance/natural-way-lawn-tree-care-in-lake-orion-mi-38001504/). File one yourself under "selling practices" since they are openly defying the DoNoCall rules. Also file a complaint at donotcall.gov.
You might want to give the office manager a call too. Patty Berriman 248-814-0588 4 Waterview Dr, Orion, MI 48362.

They are ovbiously scumbags -- give them a dose of their own medicine.
