Worst customer service ever

I hope this letter finds you well. I am writing to express my dissatisfaction with the customer service I recently received during a conversation with your consultant Nonkululeko today [16/01/2024]. My name is [Nqobile ZOndi], and I am a concerned policyholder at king price which was sourced by Nkuli (a broker from Memepe insurance brokers) for me, i sent her a message informing her that the insurance she got for me debited twice the pro rata as well as the premium, instead of assisting me she told me (in writing) that unfortunately she was not part of the call when i spoke to the people at the insurance so she doesn't know what i agreed on, im of the belief that as she was the one who requested for king price to contact me she would know what my policy entails, even worse she has the policy document which outlined all the information, Nkuli told me i did not ask for assistance i just sent her a message, i dont know how else i should have asked her to assist, i believe notifying her as my broker that i have 2 debit orders which ran on the same day is enough to show that im not happy and i need her services, she further told me she is not paid to deal with my attitude and if i want to cancel her as my broker i must do it myself and call the insurances, yet when i was applying i have never had to communicate with the insurance companies without her, so i believe she is the one liable to call the insurances and remove herself as she did when she was applying, she refused to even attempt finding out if they insurer was right or wrong by debiting me twice and all she did was to block me so i will not communicate further with her, i am now stuck with a broker that cannot/ refuses to assist me. Please assist.
