KP*** - Terrible service

Terrible service from King Price.I emailed a cancellation request on 27/10/18 I called and cancelled my insurance on the 29 / 10 / 18 as my vehicle is sold. Debit order still goes out on the 05/11/18 and I am charged R100 by my bank (FNB) for a returned debit order due to insufficient funds (I didnt need to leave funds in my account as I cancelled my insurance a week before). Call them on the 6/11/18 and ask for a reversal and the agent advises me that my insurance is not cancelled and i am put through cancellations again and my luck, i get to speak to the agent that cancelled my insurance the previous week. He advises me that the previous agent doesnt have authority to fully check my policy but he assured me that its cancelled. I advised him that I am calling my bank and reversing the debit order and he said that is ok. on 09/11/18 i get a message from king price stating that my premium has not been paid. 3rd call to king price agent apologises for the mishap but assures me again that the policy is cancelled. on 16/11/18 i get a message from king price that my premium has just decreased! 4th call to king price I ask to speak to a supervisor as I have had enough, and I am put through a Lisiqua. She apologises profusely and assures me that by end of business I will get a confirmation that the policy is definately cancelled (did not receive a confirmation as yet). on 17/11/18 a king price debit order of R706.99 goes off my account!!! Its come back as unpaid debit due to insufficent funds in my account and my bank charges me R100.00 for a returned debit order AGAIN!

I am utterly shocked at the service i have received from king price. after speaking to 4 agents and a supervisor my insurance is still not cancelled! Ive already been penalised R200 for something that is not even my mistake . I really done know whats the way forward. Please assist.
