Bad broker service and handler of complaints about the bad service gives to clients

I had a motor car insurance with PSG since 2020 with my broker as Mr Johanness Seema, excellent service from him, until I was given Mr Justice Chuene who messed up my cover because of his non communication. I asked for a lower premium on my insurance and did not update on the system. The debit order didn't go though because of this and I alertr him of this and he said he would fix it. The second month same thing happened. Until I was told that they would be canceling my insurance as I had two debit orders bouncing. I wrote to his Supervisor alerting them of this issue, imagine my surprise when he was the responding to me telling me that even if I complain about him the complaint will go via him. Instead of reinstating my after he reassured me that since it is his fault he will rectify this mistake. He then said that he would have to reroute my policy to another insurance with the promise of reinstating my policy with PSG as I enjoyed my benefits there and this was his own doing, but never did. The work relationship went sour and trued reaching out to his supervisor but instead I received calls from him telling me that I will still have to deal with even if I complain about. The arrogance of Mr Justice Chuene really *****ed a beautiful client/broker relationship I had with PSG, I only received a response from his Supervisor saying that Mr Chuene is handling the complaint even after I tried telling them Mr Justice Chuene doesn't know what he is doing. He ruined a good thing and no one bothered to call and find out how this has affected. Justice Chuene doesn't know what he is doing and his arrogance to his bad service is shameful and clearly thinks he can get away with it. He is also pleased that he can mess up and handle his bad service complaints himself. I would like to commend Mr Johannes Seema for having given the best service when I started with PSG, clearly his shoes were too big for the shameless Justice Chuene.
