DISCOVERY INSURANCE & CANDID 20 TWENTY BROKER BAD SERVICE

I had car insurance with Discovery for 4 years, and when i needed to submit a claim for the first time, i was told by their consultants that my insurance was cancelled without my knowledge. And was told that I must get in touch with their Brokers (Candid 20 Twenty), of which I wasn't even aware that the consultant who helped with this insurance doesn't work for Discovery because the email address & signature of the consultant had Discovery working details. I was told by Discovery that the Broker was informed of the cancellation that I was not aware of. The cancellation happened because I changed my banking details. However i called Discovery, told them that i changed my banking details and they gave me their banking details, including the reference number, which was my policy number. I then paid into this account for almost two years. But i am not able to claim because for some reason, they were allocating the funds and cancelled the policy. So now they say, this Broker (Candid 20 Twenty) company must fight to get the claim approved, while i wait for almost three weeks now. The Broker's service is so poor, I was calling almost every two days with no response. Get told they are investigating and they don't have answer for me. I am not happy, not sure what to do to speed up the process. They convinced me to move from Budget Insurance to Discovery Insurance, of which I never had any issues with Budget, their services have always been the best. I have now gone back to Budget Insurance because, for some reason, my car was insured and i was not aware.

So now I still need to get my car fixed, what to do with this kind of service??? I am so disappointed with the service from Discovery and also these Brokers they have partnered with.
