Car Accelerates On Its Own problems of the 2003 Volvo S60

On 12/22 I was driving my 2003 Volvo s 60 awd. I was very slowly and carefully pulling into a front in parking spot. I was particularly careful because there was a driver sitting in the car parked to my right, and I did not want to get too close to his car. With my foot on the brake I was slowly moving into the spot. My front fender tapped the short concrete barrier at the front of the parking spot. The next thing I new, the car was rapidly accelerating forward. I was worried that I would go over the barrier and strike a brick wall in front of me. I believe that the engine block must have hit the short concrete barrier and that is what ultimately stopped the car. Despite the fact that I was inching into the spot at the slowest possible speed. The force of the acceleration was enough to crumple the whole front of my car, crack the windshield, and cause the passenger front air bag to release. I feel very certain that this represented unintended acceleration. I do not think there was any chance that I stepped on the gas instead of the brake. I am a very careful, cautious driver, and was very aware of what I was doing at the time without any distractions. I reported this to Volvo customer service, who claims that after inspecting the car, they found no safety concerns. I am concerned that having Volvo do their own inspection represents a conflict of interest.
