Battle to cancel MiWay car insurance policy

On the 12 Jan 2016 I have canclled my insurance policy with MiWay via their website. The same day I send an email also via their website informing them of my cancellation. I got no reply/response.<br> I again sent an email on: 18 & 21 Jan. Then again on 15, 19, 22, 23, 24 & 25 Feb. I only got the auto reply and a read report. They tried calling me twice, both times I was not available. They sent me an email to say Busi called with the email address for Busi. I repled to it the same day, but got no response. They dont even try to call back another time.<br> They so quick to sign me up but it takes so long for them to cancel. I wonder if they take so long for a claim also.
