Dangerous Fumes from new urban Cruiser

I purchased a brand new Urban Cruiser 1.5L XS model in March 2021. As with all new vehicles there were a couple off issues which I alerted the dealership to. Of particular concern to me was the constant fuel smell in the cabin driving in excess of 100km/hr. When I took the vehicle for a service at 15,000km, I specifically mentioned it and asked it to be sorted as it posed a risk to my pregnant wife and myself. Upon picking up the car, the dealership being Mcathy Toyota Ballito, said its been resolved. A week after driving the car and the smell of fumes/petrol is still present. I have to drive with the aircon on to mask the smell. Upon receiving a customer satisfaction call of the service, I again mentioned that the issued was not sorted. All I received was an SMS with a case number and no call and its been months. Im sick of the brand!
