Bad service from wesbank

My mom has been waiting for her vehicle insurance to finalise her claim for over a month now, all because of wesbank. Amanda Gumede promised to send the settlement letter to the insursnce and never did. No interim feedback is being given or an update . We have to call in and send emails with no success. This is rediculous that you treat your clients luke this. I have sent in a query to wesbank yesterday and still no feedback. Including numerous calls and emails sent aswell.
