Home Depot-Maytag Dryer

I bought a new dryer with a moisture sensor because it was recommended to save energy and money. It was delivered April 1, 2008 and has not worked properly since delivery. The dryer shuts off automatically but the clothes are not dry. I have been in constant communication with Home Depot, A&E Appliance Repair, Cornerstone Appliance Service, and Voyles Appliance Repair, and Maytag. They all keep telling me I don't know how to use a dryer and just because the dryer doesn't work the way I want it to doesn't mean the dryer does not work. The whole point of buying the dryer with the moisture sensor was so the dryer would not keep drying dry clothes. It is supposed to shut off when the clothes are dry. What is does is shuts off and the clothes are still wet. I keep being told its my fault.
