OK, my bill for hughesnet was $108.70 every month. I have automatic draft and when it was taken out at the end of Sept for my oct payment they took out $114.07, an increase of $5.37. When I called about the increase I was told it was due to taxes on the phone service, NOT the internet. Since my contract on the phone was up I had it discontinued. I received a refund for the phone service for Oct. which posted as $29.99 on my phone app as a refund. When I called back to ask about the taxes I was told the government took those out and HughesNet had no controll of that although the tax came out with their withdrawel. The taxes at that time reduced to $2.72 which was in keeping with what the rep on the phone said it would be, between $2 and $3. He even gave me a breakdown of how much went to federal, state and local taxes at the time. It has since went back up to $5.26. When I called back to ask about it I was told it was the phone tax. That came from HughesNet. They said they would take care of it. If it was not a tax on the phone they should have told me that but each time I was told it was the phone service. I am simply going by what HughesNet told me. At no time was I told the tax was on the internet. I can understand if one rep got it wrong but not 3 in a row.
You should email the state and explain the situation to them -- their response may likely be useful to you.
