I called over a month before my contract was due to expire to make sure that my account would close, and that I would not be charged anything else. I was told that I didn't need to do anything else, and my account would automatically close, thank you for your business, etc. After the end date of the contract, I was billed for another month. I called to get that bill refunded, and they said they couldn't do that, and that they were going to charge me for next month too since I hadn't given 30 days notice. I called more than 30 days prior to my contractual end date and told them to close my account. That representative lied about me not having to do anything. He could have told me to send a letter, and I would have. But he didn't, he lied.
