Harassment and Extremely bad attitude and product

We too have been harassed continuously by Mycom Trading saying we entered an agreement when we in all innocence purchased a printer cartridge from them. They continue to harass us so much and threaten legal action that we have had to take the phone off the hook. Guys! lighten up. this is no! way to do business. You are thoroughly unpleasant and threatening. You need to stop NOW!!!!!!
