Absolutely pathetic service

I was in a car accident on the 19 June which the other party was responsible for. My frustration lies with Discovery as it took them almost a month to fix a bumper. What irritates me the most is that they first couldn't accommodate me after telling me the car would take a specific period of time, for it to take way less. I was forced to find excess money and borrow from friends after repeatedly telling them that I didn't budget for it when they told me how long it would take to fix the car. Secondly, I had items taken out of my car which were valuables (my sunglasses and gym tag) which when I told Pro Line about it, they said it was not their responsibility. I'm so sick of this insurance and I want my EXCESS MONEY BACK. I will hound you every single day until I get that money back. As far as using your services again, I'm done!
