ATT To long to describe. Was not informed internet needs phone line Nationwide

Swiatch from Time warner cable and internet to Direct TV. Was told that Direct TV offered internet. In the mail I recieved a box containing a modem which needed a phone line. I do not have a phone line so called to return and cancel service within 30 days. Was told I would be getting emailed a return lable. None came. Then the bills start rolling in. No one ever came and installed anything. I never hooked up anything. Never got one byte of data form ATT. I had my cable internet through Time Warner. Then I get a bill from ATT for 189.09 dollars followe by a Credit Collection Services for 147.97 dollars. Called and was told since I requested to have internet through ATT that I had to pay the 1st months billing of the adjusted 147.97 dollars extortion fee for no services rendered. The Credit Collection Services phone I called was 1 617 581 1074
