Crunch Fitness review: gym membership

I was under the impression that my gym was closing when I saw an eviction notice on their door, and I heard the same from other people.
I went and got a membership elsewhere, and just yesterday Crunch decided to charge me for the months they missed out on when they were MIA.
They aren't answering their emails, and when I phoned they told me I have to come INTO the gym in order to cancel.
Shouldn't it have been cancelled by default when they close for a few months, and then randomly opened and decided to start charging me again?
