Discover Insure unacceptable customer service

My car was repaired last year in July by a Discovery appointed company. My car took approximately 2 months to repair. I have recently taken my car in for a routine service at an accredited Honda dealership and they reported the following to me: - coolant reservoir was empty - the radiator cap is after market - the radiator is aftermarket as well as incorrect as it is for an automatic and my car is manual - The radiator sensor is incorrect Discovery did not respond to my email so I called this morning (and had to hold on for about 30 mins) and was told to take my car back to the people who repaired my car incorrectly. Not only is this terrible customer service, it is an unacceptable solution. I had many issues with my original claim last year and now this. I will definitely be taking my business from Discovery Insure as soon as possible.
