Request to cancel building insurance

On the 24th of November my husband contacted ABSA home insurance via email, requesting them to cancel our current building insurance policy, as we want to move to another company who gave us a much better premium for more or less the same insured amount on our house.<br> <br> Absa responded via their call centre/email, informed him that we are not allowed to cancel the insurance without their permission. We have to forward the new policy/ quotation to them, and only after they have considered it, they will get back to us.<br> <br> I sent them an email on the 24th of Nov, requesting them since when do we need their permission to move our building insurance to another company, as by law we can make use of any insurance company of our choice, even if our bond is with them.<br> <br> Up to date neither me or my husband has had any response whatsoever, and we need to sign up with the new company as from the 1st of January 2016.
