After canceling my service 11 months ago, they showed up without advance notice and charged me. They refused to waive the fee because at the time I canceled, they still owed me two treatments I had already paid for, apparently negating the cancelation in their system. I was never contacted about the subscription being automatically renewed despite my cancellation. Then, after the first person I talked to confirmed he saw the cancellation in my account, the supervisor lied and said there wasn't a note about it. Infuriating.
Oh, and the reason I canceled almost a year ago is because their mosquito treatment service DOES NOT WORK. Do not use TruGreen. Terrible product and even worse customer service.
