Care.com auto-renewal scam Internet

Care.com's auto-renewal policy is unethical. I paid for one month of service, which, according to the very tiny type at the bottom of the sign up page, was set to auto-renew. Unfortunately, Care.com does not send any reminders or receipts when collecting payment. They simply bill your credit card the full cost of renewal. Further, when I noticed the charge and called to cancel, there is no option for a pro-rated refund. I still have to pay for the full month, even though I'm no longer in need of the service and did not knowingly agree to pay Care.com the full subscription amount.
