Don't tell you the truth

I canceled my Dish Network service and was told my account was paid in full and all I would owe was $ 17.00 for the return box, I recived my last bill it was for $ 145.00, I called and asked why the said I terminated my account early, I was never told that when I canceled my service, This should have been told, Be carefull when you cancel all they want is your money, they don't care about there customers, they just like to cut channel as keep on charging you. DO NOT GET DISH NETWORK.
