Still disappointed

I have already written a review here after 1st service. Now this is between 1st & 2nd Service. The handbrake is a total failure, the car rolls back or moves forward in a slope more than 45degrees. Had my car rolling forqard and hitting a bike ahead damaging the front bumper and fog light. Fuel smell seeps into the cabin right after refueling. During the service I have been told that the issue is common, what a failure!
