I had a contract for lawn maintenance for the year 2009. Their work was very poor but I paid all the bills. The service man came again 2010 without my signing any contract and fortunately, I stopped him on the first service. He promised to let his office know about the stoppage of the contract. But the company sent a bill for 50.62 and I immediately called their customer service who confirmed cancelling the contract and let their finance department know about it. But they have harassed me in claiming $ 137.74. I have filed a complaint with Service Alberta, BBB and am researching to file complaints with all available forums. The consumers should stop the harassment of Dr. Green by going for a class action suit against their unfair practices.
