Ready to cancel my contract, based on lies and unauthorized charges!!!!!!!

Received a letter dated October 16, 2017 that "I" had reversed serval of my payments with Hughesnet. (Which "I" had not done so!!!  Started doing my investigation concerning this and contacted the bank.  Waiting to have a refund issued to me so that I can reimburse Hughesnet)  According to this letter I have 30 days to resolve the balance. (I'm thinking ok, cool.  Gives me time to get the refund.  Because, like others here I am not a millionaire and my bills are dependendent on each check. Any differences in my funds causes major issues.)  So, on 10/26/17 I made a payment of 68.00 from a account that I only hold enough funds for specific bills such as "car insurance" (no more/no less), and was going to make another payment towards the remaing balance this friday while waiting for my refund from the other bank account.   Next thing I know I receive a e-mail from my car insurance that my payment could not be processed.  HMMM, I know I put the amount on that card, so I look it up.  Well wouldn't you know Hughesnet charged the remaining balance of $206.37.  Now I sit here with a vehicle with no insurance, will have fines out the ***, no way to get back an forth to work (which means no money to continue paying my "HUGHESnet bill",  and a letter stating I have 30 days that apparently means nothing.  When I processed the payment  of 68.00 I selected to NOT keep this card on file and I DID not authorize this 206.37 to be taken out.  I've e-mailed about this more than once the past few days and keep getting the run around about auto pay and all that mumbo jumbo.  Plain and simple this is just absolutely wrong.  I was not given the oppurtunity to resolve this and instead was put in a major bind.  (not to mention that the service is not as great as I was originally led to believe, but, that is a whole nother story)
