Direct TV - the worst!

Direct TV could possibly be worse than Comcast and Verizon.  I signed up for direct TV in January, I live in Florida where there was little rain in January. Now that it is rainy season, it rains heavily every day and we loose service. Everytime!  They sent a technician then tried to charge me for a service call .   It rained once since, and we lost service. Now they won't let me out of my contract!  Does anyone have any suggestions?  Seems like I should be able to cancel since it doesn't work in the rain, especially since that it when we watch TV the most!
