Cox Communications Lied about installation costs and return locations and promotions Las Vegas, Nevada

I was given a flier by cox stating they had a special for 3 months on their cable.  I was told by the installer that he could give me a special on phone and internet.  I recuieved my first bill and it was outrageous.  I was charged for installation items that were not disclosed and the special rates were reduced or eliminated.  Called as soon as I recieved the bill and was told that the only thing I could do was return the modem and dvr box.  When I asked where the items were to be returned I was informed that the only location was the Ranch office 20 miles from me.  When I arrived at the office the line was out the door,  when I pushed for some help I was told that I couldd return my equipment to any fed-ex Kinkos,  driving another 20 minutes I returned my items.  While at fedx I was told that people are only informed of this additional drop off if they make a stink at the main office.  I then called cox and said that i wanted to be sure that my service was closed up, they said it would be billed until the return date.  I asked one last time if they could reverse the unauthorized setup charges and after speaking to a msupervisor told me I had gotten agreat deal on these charges and there was nothing they could do unless i wanted to go back on hold.  10 days of service for a hundred bucks and they couldnt remove the 30 do9llar installation,   they lied, misled and wasted my time,  dont use them try embarq.
