I have a similar problem with MyFax. I sent them an email (firstname.lastname@example.org) telling them to Close my account Mar, 2016.
This month (Nov, 2016) my account was low ($4.00) and when I checked my balance I was 6.00 overdrawn. MyFax took 10 dollars out of my account. The one I closed 9 months earlier. I emailed them again and they told me to call a number to close my account.
As far as I knew it was already closed. The didn't tell me to call any numbers when I sent the first email closing my account. Free accounts are billed regularly after the first month unless cancelled within 30 days.
Canceling is easy by phone or online. (Email is online)
