Angry debit order

On the 20th July i went to look at a car and i bought the car the dealer told me that the something is wrong on the car and needs to be fixed they will sent it to the garage I called outsurance and told them to add the H2 to the policy and they did and i would have gotten the car on the 26th and i didnt so i called them again and told them i will get the car on the 29th and they should not cancel my current car insurance but they did and i paid the prorata on the new car. on monday the 29th i was told that i will only get the car on the 01/08 and i called outsurance again and then i was informed no car except the h2 is on the insurance so i spoken to justin muller and he tried to fix it this was on the 30/07 and he removed the h2 and added my old car back and then the next day i spoke to mellaney and i told her that justin did try to help so the old car needs to be removed and the h2 should be put back and she told me that there is no prorata but i did pay prorata the same day and today on the 1st outsurance deducted a crazy amount of more than r3000 from my account which is not stated in the contract like that so now you broke my contract with you , what are you going to do with the fees on my account and what are you going to do with the rating now ? Just i want something to call me and let me know how you will fix this big problem and pay my money back that i have paid , R290 on the 26th , r150 on the 30th which mellaney told me that i will not pay and now R3066.74 that was taken off and my schedule shows it should be R2099 so it looks like i have paid all the prorata fees and all my cars which i dont have !
