Not happy at all

I got an insurance with them for my 2 card which was not a problem, later in a month things changed that I could not control, I had to move from the address I was staying at to a different address, so it meant that it was still 2 cars under my insurance but difference location, I communicated with them and they told me I can issuer 2 cars under my name on 2 different addresses, so we agreed to cancel the insurance. I reinstated my old insurance, not to my surprise this morning my account t was debited
