DIRECT TV They had me sign a 2 year service agreement without me knowing anything about it. Internet

I was trying to get away from cable because the cost was going up quite a bit.  I heard that Direct TV was great and that might be the best way to keep my rate down.  When I called, the sales people would not let me get off the phone.  I should have just hung up but I didn't.  I told them that I didn't care about how good the channels were on Direct TV.  I just cared about keeping my rate down.  I told them over and over that I just didn't see the savings because I had to go with AT&T for Internet and Phone and that rate was very high.   They specifically told me that I could cancel my service at anytime, if I didn't like it.
