Buyer paid me $22.48 for 2 aromatherapy oil diffusers. When she received them, she politely complained that they didn't work. She stated that she wanted to attach some videos but that it wasn't allowed. She was well spoken, articulate, and convincing, complete with sad & smiley faces. Unfortunately, she was also lying. I shipped her out 2 more diffusers & when she got them, she again complained they too didn't work. The odds of all 4 diffusers not working must be something like 1 in a trillion. I have had only occasional complaints about the aromatherapy diffusers, so for her to tell me all 4 of them don't work at all...impossible. I was doubtful when she complained about the first 2 but willing to believe her the first time. Now I am thoroughly disgusted with this woman. She is a master manipulator, with no conscience, exhibiting anti social behaviors & does not care who she hurts.
