I just went through similar experience. My one month membership became multi-month and I'm into the company for over 300.00. My mistake for not seeing the charge on my card. Could NOT reach them by phone but did call my bank (Chase) and they will block the next charge. FYI - you must call your bank and log a complaint before they can take action. If Care.com
hits my card again, they can get involved. Did finally get a call from Care.com
and she confirmed that no, they do not send an invoice monthly -- up to consumer to check account. I told her I was not able to delete my CC from her account as the delete button did not work. I specifically asked to have all my information removed from their system, including card and she was able to do this and sent confirm stating this was done. Buyer beware! Do not sign up for anything on this site that requires your credit card!
