They make it incredibly difficult to cancel your account. They do not allow you to terminate your account online or through email.
They require you to call customer support or write to them through the postal mail. However, every time I called customer support (I had others call as well), the operator claimed they could not hear me and abruptly terminated the call. So there is no other option than for you to have to write to them to close your account. Meanwhile they get to sell your data.
Even if I mail them, I'm not convinced they are going to honor my request to close my account. Not happy with their "customer service."
