Call and ask for the "Retention Dept".
My cable bill went from $108 to $185 since my 1 year contract rate was up. Called, got the right people and had them put me on the new customer plan.
$115 w/Starz and HBO, internet, HD-DVR and phone. I didn't have phone or Starz before and could careless about them but was part of the special they were running so here they are.
