no service at all for third party claim!!!

I am beyond frustrated trying to sort a third party claim. Forms originally sent through on Wed 18 July to claim for damage to my bumper caused by a Discovery Insure client. I can never get through on calls placed to Robyn Job who has been assigned to me, she doesn't respond to emails, neither does her supervisor answer calls or return emails. The last correspondence I received from Discovery was on 31 August the only time a phone has been answered was to find out that they hadn't even allocated an assessor to my claim, although they seemed to think the claim was in its finally stages- I have had no further response to emails or many many missed calls which they don't answer. I am a Discovery Health member and have a life policy with them, we were contemplating moving our insurance over but will definitely not based on the lack of service and the extreme frustration I am dealing with. It has been 2 months and I still have a damaged car!
