I didn't read all of them, but the first, "Golds" caught my attention:
== SNIP ==
"I am currently on the phone (and have been for an hour) with ABC Financial, the company that handles billing for Large Gym chains Golds Gym, Lifequest Fitness (I'm sure there are others).
I've been trying to cancel my membership. I've been put on hold 4 times."
== SNIP ==
I've never had a gym membership that, by default, could be canceled via letter/fax/phone call. They all say the same thing,
"Come in to the gym in person, and cancel the membership."
Most of them also have a clause saying that you are renewed for a year if you don't cancel on your anniversary.
I always add a half dozen riders (and have the manager sign it) that says things like "If I get a job or move more than 25 miles away from the gym, I can send in a letter stating that, and cancel via registered mail." - Gym managers are usually reasonable, and will let you do that. Take 15 to 20 minutes to negotiate your Gym contract - you do realize it's a contract, right?
In 90% of these cases, people just aren't demonstrating personal responsibility for the contracts they've entered.
I'll say it again - never, ever, ever enter a recurring contract (or something that might _be_ a recurring contract) with your credit card, unless you have 100% control over the cancelation and terms.
