at&t direct tv over charged me, false advertisement little rock arkansas

when i started my service all i wanted was internet. the company said they will add telephone for 2yrs for free. the 1st month bill had telephone service added which was an extra $40. i called them to put my money back, they said it will go back on my card. a couple weeks later it was not and they charged me additional $60. i called again and he said he will credit me back all my funds for the troble. i called the following month phone service was still on my phone all while i'm still getting charged for it. i called back and wanted them to disconnect my service because all of the inconviences and i told them i would be returning their equiment back. took to post office. next i got a bill saying i owe $267. i should not be charge for any of this because it was the worst service i ever had in my 46yrs of living. hope you can solve this matter because i do not want this on my record or credit.
