Budget the worst insurance company

I have comprehensive car insurance with budget for more than a year. When I took the policy it sounded like the best insurance company. In October I made a claim my car was taken to a repair shop in Randburg. They swapped my entire OEM engine and components. Before taking the car to Geartronixs for repairs I called budget and advised that the vehicle is going in for repairs and confirmed on call that the car will be insured while at the repair shop. Once a peril occurred they rejected my claim then their dispute resolution asked for prove to enforce action on my claim. I took the car to Volkswagen and showed them with pictures that my cars identity has been altered therefore making the car an ******* vehicle. They still did not take action after I provided legit proof. Then they have friends at the NFO who are choosing what evidence to use in their report. I clearly advised them that on my phone call the agent accepted my policy will cover my vehicle parts or for any losses that should occur while the vehicle was at Geartronixs. Now they holding my call records up after I asked them so many times to review it before rejecting my claim. To date nothing has been done I am paying insurance for all these months including this month and January. I have car hire. My family and I can not travel this holiday due to this and Budget just refuses to address my claim appropriately. As per law my call recordings is what is accepted at the time of taking out this policy. Now they holding my information prolonging my claim, leaving my family and I in a difficult situation during the holidays because they do not want to do what they accepted under my policy. They never even gave me a claim number yet and it's been almost 3 months. I will probably have to take this up to court. Imagine having insurance and you have to go through all of this. My previous insurance company Discovery was more expensive but I never had an issue when it came to a claim. Biggest mistake leaving my other insurance company.
