On 1/28 I received a bill for Direct Tv from Centurylink that was nearly double. I called Cust. Serv. and they connected me with someone who gave me a DISH plan that I could afford. They send me a confirmation and return label for the modem which I returned on 2/2. They kept billing me, adding late charges. I called numerous times, two people said someone would call me, two more just hung up on me. My letters with copies were disregarded. AT&T send me a credit balance, but CL discontinued my internet in June even though I paid $122.22 each month. My balance (according to CL) is now $548.88. HELP!
