Even a broker cannot get assistance or feedback from Discovery Insure

If I could give a ZERO rating, I would. I have been battling with Discovery for weeks now. Sent numerous Emails and phone calls were made without any success. I have been trying to update a claims history letter but NO ONE seems to be able to assist us. I have been sent from one department to another without any success. I have been told that I am rude and that they will not put me through to other consultants with my " bad attitude". I am a broker and will take this matter a lot further if I don't get feedback very soon. Even my official complaint to Discovery has not yielded any response. My last reference for an email sent on 22 January was ***. I will not phone again and be belittled by your *********** staff.
