Worst insurance when it comes to client services

We called First for Women to cancel car insurance. Instead of doing what we asked they say they will reduce it for us and would not cancel, because we wouldnt find a cheaper premium anywhere. Even after we specifically said it is not a negotiation but a cancellation. then we still had to call them back only to be told to give them 48hrs to cancel. On top of that they say you have to send an email to cancel- which I did, and they debited the premium after we had sent the email.
