DISCOVERY AND BROKER WORST SERVICE EVER

Due to circumstances I had to change my medical aid to a lower plan. I submitted the request on the 1 of November. I had to all the following up work. My broker absolutely did nothing unless I had a question. Discovery sent me correspondence which I cant open. So when I asked my broker what is the next step. DIscovery requested a addition bank statement and an affidavit. Today is the 30th... still nothing? When I asked my broker what is happening his answer was contact Discovery and finalise it yourself. Can I get help in this regard for this ****py service
