Nightmare with cancellation of home owners insurance

I am trying to cancel my home owners insurance at ABSA. What a nightmare! My nightmare started on the 2nd of May. I changed to another insurer for half the amount that ABSA charged. I phoned ABSA to cancel and they instructed me to mail the new policy to them. After doing so, I did not receive any feedback. I sent 4 emails asking for feedback - no response. Then I phoned again. I was informed that they have a back log on cancellations and that they will immediate attend to the matter. No response was received. Then I phoned again on 30 May. The consultant told me that she will attend to the matter the same day, which she did BUT my request was DECLINED due to an issue that they had with the address of the property on my new policy schedule. The irony is that it is the EXACT same address that appears on my ABSA policy, since I sent the ABSA policy to the new insurance company . After this, I contact the ACTIONLINE at ***. I received a reference number C - ***4. A consultant sent a mail that this matter will be attended to before 2nd of June. No response whatsoever. Even my Private Banker cannot even get any response regarding this matter. Since my home loan is also with ABSA, I decided that I will move my home loan as well as all my accounts to another bank. I JUST WANT MY POLICY TO BE CANCELLED!!!!!
