Struggle to Cancel Building Insurance

Good day, I have been struggling to cancel my Building Insurance with Standard bank since my initial request on 27 July 2017. As a result it has left me with money out of pocket due to the fact that I could not change over to the new company I chose to be insured with. Standard banks service has become so slow whether it is regarding claims or just a simple administrative tasks. Their automated email systems are frustrating and they lack the ability to pick up the phone and speak to the customer. Even work being the fact that you cannot find a dedicated person to deal with your request. Can a senior manager please give me this last bit of service so that i can start receiving a better more effective service at my new Insurance Company.
