Unable to talk to senior management/supervisors

I have an accident claim which has been rejected due to an inaccurate evaluation of the claim and am not able to get someone in the claims management department at Discovery Insure to contact me. I have spent a lot of time talking to the call centre personnel and they are not able to solve my problem. I get promises of persons that will call me back, but nothing happens. My claim was done on the 4th of March 2015 and up to today 26th of March there has been no resolve. I have written a letter and submitted it through the channels provided (e-mail), but I would prefer a telephonic discussion on the matter.<br> <br> Good luck to anyone at Discovery Insure trying to solve a rejected claim. I hope you like call centres.
