Misleading info & overcharged

Was all fine until I realised I purchased a vehicle that did not fit the specs as advertised and sold to me. The vehicle was advertised as a model with 1.4 engine capacity, to find out it's in fact a 1.2 engine. I emailed the salesman & Weelee with supporting documents to inform them of the misleading advert and that I was charged for a vehicle with a higher engine capacity, but no one has rep**** or provided any feedback on the matter. Not happy at all
