Cancellation of Roadside Service for using 6 times in 3 yrs

I think the economics aside what many would appreciate is a Clear unambiguous statement about what that cancellation policy is.

If that was made clear in the sales information then people could avoid exceeding it and it could become another decision point in the true value being offered before one decides to join.

They must have a limit somewhere, that's obvious, But where is that limit? And under what conditions? I think knowing that would help.
