They’ve got u by the BALLS

Has anyone else had a problem with the gyms, that take your credit card when you sign up and keep loading on hidden charges, long after your membership has expired? I was just hit after xmas wtih annual fee and monthly charges for a club I no longer belong to. When I called to straighten it out, I was told that my membership automatically renews itself, and I am liable for the current month’s fees. WTF?
