Untrustworthy & unprofessional business

For anyone who is considering signing up with Zipcar, be aware that when you sign up for what they refer to as a “rolling monthly no commitment membership plan” in their FAQs they will actually lock you in for a 12 month period even though this is not explicitly made clear on their website. When I asked to cancel my membership after a few months, they made a one-off charge to my credit card for the membership fees that would have been paid over the remaining months. They could have called me to explain that it doesn't make sense to cancel my membership as I would still be billed the full amount but would not have the benefits of membership, but no, they decided they should get to have their cake, and also be able to eat it too. Greedy, greedy business....
