Worst Bank and Service ever

Worst service ever from a bank. I put a home insurance claim through on 29 October, and a contractor was sent, he literally spent 2-3 minutes on site,. I had to request for feedback on the 5th of November as the bank was quiet, the feedback was that my claim was rejected and on the same day, I sent through an email for the decision to be reviewed as advised and again I had to request for Feedback on the 11 November, to be told again that their decision stands. I'm not even sure why I still have my bond with Nedbank, I guess I need to go to where there is better service. :(
