Standard bank home insurance

I have requested my home insurance that is with Standard Bank to be cancelled on the 6th of July 2021. On the 21st of July i have received an email indicating that the new insurance that I have with Outsurance is not sufficient as my proprety value must be R2,9 million on the new insurance and not R1.7 million, because I have an outstanding bond account of R39,000 on the property. Then i decided to pay off the outstanding bond account in order for the cancellation to continue. I have paid the outstanding amount on the bond account on the 28th of July and once again requested to cancel the insurance as I already have new house insurance. Then all the sudden they want to give me a better premium because I want to move. I told them that I do not want to use standard bank anymore as there customer services is bad. Then on the 3rd of August the insurance premium was once again collected against my bond account. I have send through 6 requests to cancel the insurance and to send me prove. Nothing happens. When I visited the branch there is no consultant that can help you you must call the call Centre from the bank hold on for an hour and still no one to assist you.
