Questionable claim process

I had my car insurance with outsurance from the day before I collected my car from the dealership. A month before I decided to sell the car, I put in a claim for a cracked windscreen. The glass company contacted me to notify me that they received my request. One of outsurances agents contacted me to say the claim has been received and is approved. I started contacting the glass company and outsurance weekly to find out when my windscreen would be replaced. They kept making promises. In the end I sold the car without them ever replacing the windscreen. This was the first time I had to claim from them and they let me down. It just makes one wonder will they pay out ur life insurance, home insurance ect when u need them....
