I had att dsl from sept 2007 to dec 2010 and had the 6.0Mb/s,and then switched to Charter. Well I had to go back to att dsl a few months ago and got 3.0Mb/s down speed. Yet when I tried today to upgrade to 6.0Mb/s down they said it isn't available in this area. They said they can't go higher which is complete bullshit,They could go higher then 6.0Mb/s if they wanted to. If I contact their business section could I get it increased?
