Non existent service

I cancelled my life insurance via e-mail on the 6th of January as I took out other life insurance. I received an e-mail advising that my request was forwarded to the relevant department. To my surprise they deducted for February already. This is my second problem with 1Life. First my late sister in law had a policy with 1Life. It took me almost a year later to post on Face Book and HalloPeter to get them to pay out and now this.....?
