I used TruGreen's services in the spring of 2015, and starting in mid-summer, I started getting sales calls for additional services. Most if not all of the calls were from a sales rep named Sam. I repeatedly requested that I not receive calls, especially since Sam was very aggressive in his approach. As of March 2016 I am still getting calls, usually without a message left.
I informed a manager months ago that I will not use their services again, but the calls will not stop. Since I've been a customer in the last year, the Do Not Call list does not apply yet. At this point I've submitted another complaint, and hope it will be referred to the president.
