This complaint is coming on a long way. I wanted someone to call me back so i change my banking details. Three days later i had to call myself and make a noise when the switchboard lady transfered me to someone else. The lady changed my details but my household insurance is still todate debited from my old account. I now want to cancel my insurance and no one is still calling me back. If this is the service i receive how do they handle the claims. I am really not happy with the service.
