Brolink refuses to cancel my insurance

I would to know depose brolink for the disgusting service I have received.in may I out in a claim on my insurance. Firstly I had to call them all the time to follow up on my claim. They then eventually gave me feedback and referred me to the nearest Pannelbeater. Took my vehicle there and they took almost 3 weeks to repair it. One person said that they were waiting on doors form jhb. The other said his going out to physically look for doors around Cape Town. My kids and I walked in the rain to use public transport. Eventually my vehicle was retired with unfinished worked. I spoke to the assessor and he helped me so well and arranged for a courtesy car to use. Up until today I have never heard back from the person who deals with the claim with regards to getting my excess fee back. He told me about 6 months ago that he is awaiting from the traffic department to get back to him on information on the other driver. Heard nothing to date yet. I decided to cancel my insurance a few days ago and managed to get a cheaper and better insurance from another service provider. I sent my new policy through to Brolink AIPservices and asked them to cancel my cover. My new cover only starts on 1 December. I made a payment in October to cover my vehicle for November. They are refusing to cancel my debit order in November. I don’t see why I should pay 2 insurers to cover 1 vehicle for December. I should not be paying in November with brolink to cover me for the December when I will start my new cover in December. This is *********.
