Really bad service & panic alarm appeared not to work

We arrived where the car had been parked just as it sped away. I pressed the panic button at least 25 times and got no response. I had to find their number and call in to report the loss of the car. If they had responded to the alarm, there would have been a much bigger chance of getting the car back undamaged. I am now very worried that the alarm won't work if I'm ever in the car needing help. Also, it took hours and a lot of persistence to actually get hold of someone who could send me the information that the insurance company required an despite having raised a complaint about poor service 3 times I am yet to have any acknowledgement or response.
