This is a high-pressure sales that I regretted as soon as I finally got to leave the initial appt. She quickly went over the contract which I signed, and she failed to give me a copy. I called within 24 hrs and cancelled the contract, or so I thought. After reading the above complaint stating the requirement of sending a certified letter, I did so and then stopped by to ask them for my copy of the agreement. They were quite nasty, and so was I. Later I received a call saying that my money would be refunded. Of course, I already had contacted American Express about disputing the charge. Apparently, these people care nothing for ethical business practices. Shame on them.
