2019 VW Polo Conceptline 1.6 at VW Woodmead - The worst acquisition ever!

I bought a 2019 VW Polo Conceptline 1.6 at VW Woodmead in September 2019. l curse that day because despite the car being 1.6 engine, it has no power at all. Worse, it chows gallons of petrol when I travel to KZN. When driving my bigger turbo-charged car, l never refuelled after the tank has been full. What compounds it all is the way it was marketed to me as the best newbie, but now my salesman is running away from me.
