Bad service

Changed the details on my bond profile into someone else's name so I can't receive a bond statement. 3 weeks of begging for them to rectify it and still not done. I have given them a copy of my title deeds. Nobody returns my calls or responds to my queries. Branch can't help. They keep telling me I don't have a bond with them but they take my money monthly. Lodged a formal complaint and still nothing. Leave messages which are not returned. Emailed, called and been into the branch numerous times.
