Unable to get a response out of these people

On 17 MArch I requested to have my risk address changed as we were about to move house on 27 March and to provide me with a quote for my building. Well, to date I have not received any confirmation that my risk address was changed and after 4 follow up emails I still do not have a quote for my building insurance. What do one have to do to get information out of this call centre? Cancel the policy and move elsewhere?? Standard Bank Ins and Verseker was able to provide me with a quote within 30 minutes. Would really suggest you get your act together or you will lose a number of customers...I am for sure starting to shop around.
