Sanlam Sky - worst policy and worst service!!!

I signed up for a Sanlam Sky policy in 2007, later realizing that the policy is not worth it and then I tried cancelling a R60 policy for the last 5 years or so. I have lost half of the proof of cancellation, calls are recorded but where is it? Emails are not being responded to etc. Its terrible! Hopefully someone will respond to this.
