I have been trying to cancel my membership with these shady people for about a week. When I call, they keep me on hold for 30 minutes only to hear at the end that the "office is closed. Please call back during normal business hours." Then they go on to list the business hours are from 6 am to 6 pm. I call at about 10 am every time!!
There is no clear way to cancel online either. You are only allowed to "downgrade" your membership to a cheap or more expensive option. So annoying.
They are sketchy ***. Avoid them.
